Draft Defense Often, but Offense Early

Pete Carroll and John Schneider have presided over 3 Seahawk drafts now. During this time they have used the draft to effectively rebuild the entire roster.  From this limited sample set, can we make a declaration of their overall draft philosophy and trends or was it more a matter of needs and availability?  I suppose we will add one more draft to the data collection in the next couple of days.  But what can we learn from the previous 3 drafts compared with the 16 prior Seahawk drafts (since 1994 when the draft moved to 7 rounds).

Over 3 drafts since 2010, Carroll and John Schneider have used 28 draft picks. Of those 28 picks, 19 (68%) of them have been defensive players leaving 32% on the offensive side of the ball.  Not surprising considering Pete Carroll is a defensive coach and inherited the 23rd ranked defense.

pc_total_distHowever this distribution is in pretty stark contrast to the previous 16 years where 52% of 123 total picks used were on the offensive side of the ball.

1994_2009_total_dist

 

 

So the Hawks have drafted heavy on the defensive side of the ball and while I anticipate that will start to even out in the upcoming drafts, I think when we drill down on WHERE in the draft these players were selected, we might start seeing a philosophical trend develop rather than just need based drafting.

So we have learned that out of 28 picks, 19 have been used for defense. But of those 19 picks, 16 of them have come in rounds 4-7.  Only 3 picks in the first 3 rounds have been used on the defensive side of the ball.  That is an incredible 80% of round 4-7 picks being used on defense in contract to 62% of Round 1-3 picks being used on Offense.

pc_1_3_dist

pc_4_7_dist

 

 

That three year data shows we draft defense often, but offense early.  I do not believe this is just by chance.  We have learned from listening to both Pete and John that they covet unique characteristics.  They do not evaluate players like the rest of the league and as such, they look beyond what things a player can’t do, and look at what they CAN do with these unique traits in their particular scheme.  I believe that diversity is much more prevalent  and exploitable on the defensive side of the ball which allows them to target guys later in the draft that are not as highly ranked on other franchise’s draft boards.

So far the results have been amazing.  The core of one of the top defensive units in the league has been built largely on later round draft picks, allowing the team to focus on offense in the early rounds.

With very few immediate needs as we enter the 2013 draft, will be interesting to see if they keep the same approach.  I fully anticipate the team drafting more offensive players this year as the total spend on the offensive side of the ball is going to have to drop in the years to come in order to keep the defensive core together in a Seahawk uniform…. that means replacing some higher value contracts with rookie deal contracts.

Rushing by Location

Previously I have posted Receptions by Location and YAC by Location so it is time to look at the Seahawk’s ground game by location, or more specifically by “hole”.  Using data from ProFootballFocus,  we will take a look at Attempts, Yards, and Yards per Rush by hole.

attemptsholes

 

38% of the Seahawks rushing attempts came between the Center and the Guards.  Not surprising considering the power running game approach of the coaching staff and the skill set of lead back Marshawn Lynch. 

While rushing to the outside of the guards, the Seahawks were extremely balanced in their running rushing 161 times to the outside of the left guard compared to 158 times outside of the right guard.

 

yardspercarryhole

 

Despite the “3 hole having only the 3rd most amount of attempts, this hole is the leader in yardage.  All 5 “runners” in the above chart had their best yards per carry in this hole.  For the amount of attempts in the “2″ hole I would have expected a larger return in terms of yardage.  The revolving door at RG certainly is reflected in the yardage performance here.

 

yardspercarry

 

The “8″ holes shows up as the best performer in yards per carry.  That number is obviously enhanced by Wilson’s 105 yards but surprisingly, at least to me, Lynch performed  exceptionally while running to the right end.  Keep in mind that 77 of his 200 yards in this hole comes from one run in the Week #8 game vs the Lions.

Keeping the focus on Lynch as he accounts for the large majority of carries, in general he had more success running to the left.  A data element that I would love to know is the breakdown on how many times he when he ran left was it the “strong” side of the formation or whether they were in double TE set.  

Despite not having a more granular look at the results (ie. by personnel, by formation, etc) I think some interesting information can be found here.  It was a very successful season rushing the ball however the team could stand to get more consistency from the RG position.

Average Draft Round for Top DT’s and DE’s

With the 2012-2013 campaign concluded, the 12th Man turns their attention to the upcoming NFL Draft on April 25th.  Debate will rage over which positions the Seahawks should focus on in the early rounds.  The consensus appears to be either a Defensive End or a Defensive Tackle.  This draft appear to have nice depth on the defensive line even if lacking star power.

I think we can all agree that despite the great defensive performance this year is that this team could use a more consistent pass rush.   Clemons had a fine season at the LEO and Irvin flashed his potential as a pass rusher.  The Seahawks dont get much rush from their strong side DE (Red Bryant) when in our base 4-3 Under defense, but that is not required of that position in this defense.   Our edge rushing was at least adequate in my opinion.

However the Seahawks failed to generate much push from the interior of the defensive line, especially once Jason Jones was lost for the season due to injury.  Many fans, me included, feel like for this defense to take the next step, finding a penetrating 3-technique defensive tackle is paramount.

This led me to take a look at the Top 10 performing defensive tackles and 4-3 defensive ends in the NFL this season in two passing and two running metrics to see where they were drafted.

defensivetackles

43defensiveends As we can see here, 40% of the leaders in sacks from defensive tackles were drafted in the 1st round.  However that same amount were drafted in the 4th round or later.  Guys like Geno Atkins and Henry Melton were absolute steals in the 4th round.

For the defensive ends, in most cases we are seeing a full round drop or more for the top 10 in their position for each of these metrics compared to defensive tackles.  Because of the small sample size the avg round is greatly impacted by the two UDFA’s (Cameron Wake and Chis Clemons) that were top 10 in sacks.

Not sure much can be drawn from this as it is only a one year look.  Based on where we draft in the 1st round it seems like a good opportunity to address the DT position however Pete Carroll and John Schneider are anything but predictable when it comes to their evaluations.  They have done a fantastic job the past few season with the draft and I have no doubt they will pull another mid round gem from their hat.

For reference, here are the total DT’s and DE’s drafted by round in the last 10 drafts.

Seahawks Draft History by Position and Round – 1994-2012

Here is the last 19 years of Seahawks draft history.  I choose 1994 as the starting point as that is when the NFL went to the current 7 round draft format.

picksbyposition

 

On offense, the Seahawks have drafted more WR’s (16) than any other position in the last 19 drafts.  This is followed by 12 tackles, and 10 TE’s.

On defense, DB’s lead the way with 27.  In my database, CB’s and Safeties are combined.  At some point I am going to break these out but my DB has every pick for every team going back 19 years so it will be time consuming.  Any volunteers?

Overall a pretty even spread with 76 defensive players and 70 offensive players.

For the above selections, here is the Top 10 schools these players were selected from.

YAC Leaders By Location

Now that we have seen receptions per receiver in each of the 12 passing zones, we now look at the YAC (yards after catch) in the same fashion.

Don’t expect to be blown away in this metric as overall the Seahawks finished 3rd to last in the NFL in YAC.

Receptions by Location

Seahawk quarterback Russell Wilson proved very adept at spreading the ball around during his rookie season.  I was interested in seeing the breakdown of who he threw to in each of the 12 passing zones so I put together this graphic showing  who caught each ball in all of the zones.

On the right side of the graphic I have listed in descending order the # of receptions each player had.  This data INCLUDES the two playoff games.

rec_location

 

It appears from this graph that not only did Wilson spread the ball around, the coaching staff did a nice job moving our receivers around.  Sidney Rice who tied for the team lead in receptions at 55 with Golden Tate, caught balls in 11 of the 12 passing zones while Tate caught passes in all 12 zones.

The same could be said for our two leading TE’s (Zach Miller and Anthony McCoy) who both had receptions in 10 of the 12 passing zones.

Receptions by the runnings backs proved to be a bit more specialized outside of Marshawn Lynch who caught 6 passes to the left of the numbers, 13 in the middle of the field, and 8 to the outside right.  Of Robert Turbin’s 22 receptions, only one came to the left outside of the field.  Michael Robinson was sent to the outside right in 12 of his 15 receptions.

Rookie QB Passing Locations

Robert Griffin III sets rookie QB rating record.

Russell Wilson tied the rookie QB passing TD record.

Andrew Luck sets the rookie QB yardage record.

All three QB’s lead their teams to the playoffs.

A remarkable and unprecedented season for the rookie crop of signal callers.  All of them had a case to be made for Offensive Rookie of the Year, an award that went to Robert Griffin III.  As an admittidly biased observer, I think the voters got it wrong and Russell Wilson should have won the award but RGIII is not underserving.  I am more perplexed by Luck finishing ahead of Wilson in the voting.

It is easy enough to compare the three with the readily available metrics of Wins, Yards, TD’,s, INT’s, etc but with this remarkable season from the three, I wanted to take a look a bit deeper into HOW their statistics were achieved.  More precisely…. WHERE …. as in where on the field did they do most of their damage and where did they struggle.

Thankfully the folks at ProFootball Focus track this data.  Here is how the “passing locations” look for the 3

* This data is based on the zone where the receiver was targeted, not where the play ends.

rookqb_rawdata

 

Some really interesting data here… but it can be a bit hard to digest.  After putting it together I found it a bit difficult to draw any conclusions easily … well at least without my eyes starting to bleed…. so I decided to convert this data into a series of “heat maps” that could be more easily digested at a glance.

I created these heat maps for Attempts, Completion % , and QB Rating.  Hope you find them interesting and informative.

The color coding of ranges are proportional to their own statistics and are not normalized across the three players.  I save that for the final QB Rating graphic where I use a standardized range to color code the charts for all three.

ATTEMPTS – Percentage of their attempts in each of the 12 passing zones

rookqb_attempts

 

Robert Griffin III – It is clear that RGIII really favored throwing to the middle of the field.  That is certainly not uncommon as throwing outside of the numbers is a much harder throw and brings greater risk. But with over 63% of his throws in the middle of the field,  attacking the middle was more prevalent than with Wilson or Luck.  Especially that short-middle zone.  Josh Morgan was the most targeted receiver in that zone with 27 targets.

Russel Wilson –  Russell Wilson on the other hand used the entire field to a much larger degree than RGIII and attempted a significantly greater amount of balls deep (20+ yards) than RGIII.  Many draft pundits felt due to Wilson’s height being under prototypical height of an NFL QB, that he would struggle in the short middle of the field.  At least in attempts, he certainly attempted his fair share of passes in that zone.  As this post moves on, we will see whether he was effective in that zone.  On outside the numbers passing, he favored throwing the ball to the right side of the field which considering the amount of times he rolled out or ended up scrambling to the right (in addition to being right handed), that makes sense.

Andrew Luck-  Luck really pushed the ball down the field.  Nearly 58% of his pass attempts were targeted 10 + yards down the field.  He also had a really nice spread between throwing outside the numbers both on the left and right sides of the field.  Clearly his favorite zone was that intermediate middle of the field.

So now that we see where they threw most often, lets look at how successful they were in each of these zone by looking at completion %, and QB rating.

Completion %

rookqb_completion

Robert Griffin III - RGIII finished 4th in the NFL in completion % and based on the attempts graphic he feasted in the zones where he threw the most balls.  He was extremely accurate in those middle zones and was spectacular  in that 10-19 yard middle zone.  His accuracy (or at least success rate) really trailed off when throwing the ball down the field outside of the numbers.

Russel Wilson -  Well I certainly see nothing here showing RW struggles completing passes in the short middle of the field.  Wilson completely scorched the under 9 yards zone all the way across the field.  But this is not a guy who inflated his completion rate by just being successful on short passes.  He was incredibly accurate with his deep passes with only the deep right zone being sub 50%.

Andrew Luck-  So while we saw that Luck threw the ball down the field more than the other two QB’s, he certainly did not have the same level of success completion % wise.  Some of that can be attributed to the Colts receiving core that dropped the 7th most amount of passes but clearly Luck lost accuracy throwing the ball deep as he only completed 33% of his passes 20+yards compared to 44% for Wilson.

QB Rating

For this graphic, I am using the same scale to color code the chart for all 3 QB’s.  The ranges I selected for QB Ratings are:

  • Under 80
  • 80 – 89.9
  • 90 – 99.9
  • 100 – 109.9
  • 110 – 119.9
  • 120+

rookqb_qbrating_comparative

 

From this set of charts, it is almost hard to believe that RGIII finished slightly ahead of Russell Wilson in QB Rating.   QB Rating is very affected by INT’s which accounts for RGIII’s rating as he was excellent in protecting the football.  On the flip side, Andrew luck threw the 3rd most INT’s in the league which is reflected in his 26th best QB Rating.

From this chart we can see that RGIII was very efficient in all zones with only 3 of the 12 zones registering a passer rating of below 90.  Interesting that his best zone in passer rating is the zone that Wilson and Luck struggled in the most, however that is in part due to not having many attempts (9) in that zone compared to 21 and 36 for Wilson and Luck respectively.  But the larger factor is that both Luck and Wilson had 3 INT’s to that zone to zero for RGIII.

The results for Wilson are truly impressive.  9 of the 12 passing zones he posted a 100+ QB rating.  He was dominant in the 0-9 range but maintained that great efficiency when throwing the ball into both the 10-19 and the 20+ yard range.

SUMMARY

While I give credit to Andrew Luck for having a fantastic rookie season for making the playoffs with the worst of the three surrounding casts, he just was not as good as the other two.  Too many errant throws and poor decisions… things that are to be expected from rookie QB’s… it just so happens that there were two other rookies that looked nothing like first time signal callers.  We also saw flashes of some good things from the like of Ryan Tannehill, Brandon Weeden, Kirk Cousins, and Nick Foles.  A really special QB class.

While it appeared at times, especially early in the season, that Russell Wilson missed seeing an open receiver in the middle of the field, it is clear that there is no area of the field this guy can not throw to.  As he says, “Height does not define him” and the pundits predictions of having trouble throwing and seeing over NFL offensive lines has proven not to be an obstacle for Wilson… at least in season 1.  But anyone that knows what this man is about would never bet against him.

RGIII may have won the Rookie of the Year award but I would put money on Wilson becoming the first of the three to bring home the Lombardi.

2012-2013 Defensive Rankings

Here are the final defensive statistics with league rankings for the 2012-2013 season. I have also included how last years team finished, after week 1 of this year, after week 9, and then how they ended the regular season for comparative purposes. If anyone wishes to see this data week by week for the entire season, please email me to dave@hawkmetrics.com and I will send it to you.

* stats sourced from www.teamrankings.com

Scoring Defense

def_rank_scoring

Well what can you say about this defenses ability to keep teams from putting points on the scoreboard!  Can’t get much better than #1 in the NFL.  Because of our ball control offense our defense was on the field for the second least amount of plays in the league so that certainly helps, but that is not artificially inflating the #’s as this unit was also #1 in the league in points allowed per play.

The 2nd half defense was just tremendous overall allowing a league best 6.9 points in the 2nd half

 

Defensive Yards allowed

def_rank_yards

This was not a “bend but don’t break” defense either as they were very stout in terms of yards allowed as well.  Not allowing the big passing plays was a big contributing factor here as the Seahawks gave up the 6th fewest 20+ yard passing plays and the 4th fewest 40+ yard passing plays.

 

Rush Defense

def_rank_rush

As pretty as the previous stats where, the rush defense has to be considered a disappointment this season.  Giving up only 103.1 yards per game looks good on the surface but considering only 3 teams in the league faced less rush attempts than the Seahawks, it is a bit deceptive.

In the early part of the season, it appeared the rush defense would be a strength, however the wheels started falling off after allowing the 49ers to rush for 175 yards in a Week #7 match-up.  Over the final half of the season, the Seahawks were one of the worst in yards allowed per rush attempt.

Hopefully new Defensive Coordinator Dan Quinn who’s expertise is the defensive line can improve the play of a the front 4 who were largely unimpressive.

 

Pass Defense

def_rank_pass

On the flip side, the pass defense was a strength of the defense.  While the team struggled defending the short middle of the field, the pass defense had a fantastic statistical season.  Only 3 teams faced opponents that passed as a % of total plays more than the Seahawks faced but still ended up allowing the 6th fewest passing yards per game.  All this while facing the likes of Aaron Rodgers, Tom Brady, Tony Romo, and  Matthew Stafford.

The coverage outside the numbers was outstanding with Richard Sherman putting up a historically great statistical season for a CB.  Per ProFootball Focus, QB’s posted a 44.9 QB Rating when throwing at Sherman.  A truly astounding mark.  Browner was not too shabby either with opposing QB’s posting a 77.6 rating against him.  The team also finished with the 8th most amount of Interceptions.

 

Defense Miscellaneous

def_rank_misc

 

Besides the weak rush defense at times, the other areas that stand to be improved are getting consistent pressure on the QB and 3rd down defense.  Although the 3rd down defense was much better in the 2nd half of the season.  Regarding pressure, the Seahawks would be wise to focus on improving on getting interior pressue which would greatly aid the pass rushing defensive ends.  Clemons had a fine season and Irvin showed promise as a pass rusher but once Jason Jones went down with injury, the Seahawks were unable to generate much pocket push at all.

2012-2013 Offensive Rankings

Offensive Scoring

off_rank_scoring

 

The Seahawks ended the season with a 5.7 points per game increase from last season.  For the first half of the season, this years version of the Seahawks operated at a level below last years Tarvaris Jackson led squad in putting points on the scoreboard.

Starting around Week 8 in a game vs the Lions, the kid gloves were taken off Russell Wilson and from that point forward the Seahawks offense soared averaging 32.8 pts per game the remainder of the season.    The Seahawks scored a lot of points but maintained their effeciency as they ended up 6th in the league in points per offensive play run.  Considering the ball control nature of the offense and with running the ball the highest percentage in the league, this is a very impressive feat.

The chart shows a dramatic improvement in 1st half scoring.  Slow starts plagued last years team as they were 24th in the league last year averaging 7.4 points in the 1st half of games.  This years squad averaged 13.8 points in the 1st half good for 6th best in the league.  The 2nd quarter saw the biggest gains from the midway point in the season going from dead last in the league after week 9, to 8th best by the end of the regular season.

Offensive Yards

off_rank_yards

 

Typically offensive and defensive units are ranked based on yards per game.  In this case the Seahawks offense was “ranked” 17th in the league.  As we know, this can be a deceiving metric if used as the definitive statistic to “rank” a unit.  Too many variables enter into this statistic (such has # of plays run, average field position, quality of the your own defensive unit, etc) and one could rightfully argue that points are the goal, not yardage.

Such is the case with the Seahawks.  Only 3 teams in the league (Tennessee, NY Giants, and San Francisco) averaged less offensive plays per game than the Seahawks 60.9.  Going to be hard to be among the leaders in yards per game running less plays per game than almost every other team.  However when you normalize it a bit (still does not eliminate many of the variables) and look at yards per play, you will find an offense that was among the best in the league by the end of the season.

Rushing Offense

off_rank_rush

 

Rushing the ball is the foundation of what Pete Carroll has wanted with the offensive unit and they did not disappoint.  Running the ball a league most 55% of the time they did so with both production and efficiency.  The Seahawks were a top 10 running attack in the league but the adoption of the Zone-Read into the offense propelled them into a top 5 unit.

While I do not expect them to get away from their running identity next season, I would assume we will not see them rushing the ball at a 55% clip, especially if defenses use the offseason to figure out how to slow down the Zone-Read.

Passing Offense

off_rank_pass

 

If as a percentage of plays run, you run the ball more than any team in the league, that also means that you pass the ball the least of any team in the league.  This again is where on the surface the Seahawks might be viewed as having a sub-par passing attack,  Throwing for only 189 yards per game to the more casual observer will do that.

But what the passing game lacked in quantity, it excelled in quality in the second half of the season.  Not only did the Seahawks end the season 4th in the league in passing yards per attempt, and 8th in completion percentage, but also finished 7th in the league in passing touchdowns per game with 1.7.

Offense Miscellaneous

off_rank_misc

Two other areas that showed huge improvement from the first half of the season to the end of the season was Red Zone TD % and 3rd down conversions.  Both of these areas were problems last year and continued to be problems early in the season but by the end of the year became strengths.  The QB being sacked on 7.5% of passing plays is certainly an area for improvement.
