NFL Cornerback Analysis Using Attack, Battle, Bleed and Burn Ratios through 12/2/20

Corners rated for Week 12!

Your weekly cornerback performance update through Week 12...let's get into it!
As usual, we use the following metrics:
  1. Attack Ratio: Total Targets/Total Snaps
  2. Battle Ratio: Passes Defended/(Passes Defended + Completions Allowed)
  3. Bleed Ratio: Total Reception Yards Allowed/Total Snaps
  4. Burn Ratio: ([Total Interceptions +50% of Forced Fumbles]/Total Snaps) minus (Total Touchdowns/Total Snaps)
These are all represented by Z score (the number of standard deviations from the mean).  "4 Score Z" is the average of the four ratios.
Qualifying cut off was 444 snaps though Wednesday night's PIT-BAL game.
Green highlight equals at least 1 standard deviation better than the mean.
Red highlight equals at least 1 standard deviation worse than the mean. 

Teams



Looking at the top 5 teams compared to the cellar dwellers and it's clear the difference is experience.  
  • #1 NYG corners Logan and Bradberry average 6.5 years of NFL experience.
    • #2 MIA corners Howard, Jones and McCain average 5.7 years in the league.
    • #3 IND corners Rhodes and Moore average 6.0 years on the island.
  • #32 MIN is breaking in two rookies starting at the corner.
  • #30 NYJ are also starting first year men after second year man Bless Austin went on IR.
  • #31 SEA is the anomaly with Griffin, Flowers and Dunbar averaging 4.3 years in the league.
    • #29 ATL returns to form with Oliver (2nd year man) and Terrell (rookie).

Player Updates

Who's Hot - Attack Ratio

















  • I have to go back and watch McCain but how is a guy on the field for 690 snaps (qualifying for this analysis was 444) but only targeted 2.0% of the time? Is he flypaper?  
    • His Z score of 4.12 is just idiotic.
  • White has nothing to be ashamed of at being targeted just 6.3% of his defensive snaps. (But it still looks huge vs. McCain, right?)
Who's Not - Attack Ratio

















  • They're shelling Kirkpatrick down in ARI, looking his way 12.8% of the time he's on the field.  Ouch!
  • That Xavien Howard is dealing with a slight case of overbombing at 11% is not surprising with McCain and Jones (who have a positive Z scores) as the other options. 
Who's Hot - Battle Ratio


  • QB Repellent McCain is backing up his insane Attack Z by also having the top Battle Z, defending a third of "won"  passes (completions plus passes defended).
  • Despite Xavien Howard being #2 in Battle Z, defending over 30% of won passes, QBs still attack him more than they should (nearly 1 standard deviation more than average).
Who's Not - Battle Ratio

  • DAL's Lewis wins on  just 3.0% of qualifying passes. Thankfully, his Attack Z is about par.
  • Pride is worse than 1 standard deviation compared to average but doesn't seem like Offensive Coordinators have noticed since he has a strong Attack Z. 
Who's Hot - Bleed Ratio
















  • McCain, again, is top of the heap, giving up less than 0.15 yards per snap.
  • Lewis made the Top 10 so he is not giving up yards despite losing a lot of his contested battles (-1.62 Battle Z).


Who's Not - Bleed Ratio
















  • Okudah is number one but on the wrong list giving up 1.29 yards for every snap he's out there which, with his Attack worse than negative 1, means OCs are taking advantage.
  • Davis is #5 on the Bleed list but at least holds his on in terms of Battle.


Who's Hot -Burn Ratio
















  • Humphrey tops the list driven by his ability to get at the ball (INTs and Forcing Fumbles) and keep opponents out of the end zone. 
  • Despite his solid Burn, Kirkpatrick is still getting shelled by OCs (Attack).  Notwithstanding, he has a  "bend but don't break" strategy, giving up yards but not scores.


Who's Not - Burn Ratio

















  • Skrine with just one forced fumble and no INTs gave up five TDs which put him at the bottom of the Burn list.  
  • McCourty and Herndon are Burn victims but each have top level Attack ratios so OCs may start looking their way more.
Who's Hot - 4 Score 















  • Duh.  Topping 3 of 4 lists, obviously McCain has the highest overall average of Attack, Battle, Bleed and Burn.
  • Of the top 10, only McCain and Ryan are greater than 1 standard deviation above the mean. 

Who's Not - 4 Score














  • The good news for Okudah is, just like wine, corners get better with time.  He has a lot of upside so if he can just drown out the boo birds and endure the trial by fire, the sky is still the limit.
  • There are far more guys with more than 2 years experience on this list than I would have expected.  Will have to keep an eye on what is driving their ratios. 

That's it for this week.  Look for the Week 13 update soon.
