NFL Cornerback Analysis through Week 11



Cornerback updates through 11/25/20

Back again with an update on cornerback performance through Week 11 using 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)
Previously, Attack included what is now broken out as the "Battle Ratio" so each represents an equal component in the overall final ranking.
These are all represented by Z score (the number of standard deviations from the mean).
Qualifying cut off was 416 snaps.
Green highlight equals at least 1 standard deviation above the mean.
Red highlight equals at least 1 standard deviation below the mean.

Player Performance




  • Offensive Coordinators throw at Tre'Davious White only 5.6% of the snaps he's on the field. When you look at his better than average Battle and Bleed ratios, it's justified.
  • Panther Troy Pride is skating because he is in the Top 10 in terms of Attack ratio but his other metrics indicate below average performance.  Will MIN be able to take advantage of this?

Attack Ratio - Who's Not?


  • SEA corners seem to have had the 'Who's Not' spots on lockdown this season and Tre Flowers is doing his part by being targeted the most when he is on the field of all qualifying CBs.
  • OCs seem to have it twisted by including Carlton Davis in the most targeted group.  Dude is nice in two of the other three metrics.  Let's see how Mahomes and Bienemy deal.
Battle Ratio - Who's Hot?


  • Jaylon Johnson was tossed into the fire by CHI right away and he's showing he belongs with the highest Battle ratio through Week 11.  He and Fuller (#10) are a formidable duo.
  • Another rookie, Trevon Diggs is on the boundary of above average but the Bleed is below average.  He is solid at defending passes, but when he give up a catch receivers pick up more yards than average.

Battle Ratio - Who's Not?

  • Dikembe Mutumbo would not have a lot to say to Jourdan Lewis as his ability to disrupt receivers leaves a lot to be desired. 
  • Although Jimmy Smith makes the list, OCs don't throw at him and he is definitely not giving up yards.  


Bleed Ratio - Who's Hot?

  • The aforementioned Jimmy Smith tops the board giving up the fewest yards per snap.  Given the above average Attack ratio, OCs are not messing with JS.
  • Jourdan Lewis, despite being picked on with his Attack and Battle ratios less than the mean, does not give up a lot of yards per snap.  

Bleed Ratio - Who's Not?

  • Welcome to the NFL, Jeff Okudah.  He has the largest Yards/Snap number but he is at least staying above the mean in terms of Burn ratio.  Barely.  Let's see if the kid is going to soak it all in this year or if this is what we should expect going forward.
  • Unfortunately neither Sean Murphy-Bunting nor Isaiah Oliver can deflect attention on their Bleed ratio to another superior metric...because they are less than the mean in all categories.


Burn Ratio - Who's Hot?

  • Marlon Humphry is a work horse for BAL with a Burn ratio more than two standard deviations above the mean.  Only Xavien Howard comes close. 
  • For some reason, OCs keep shelling Carlton Davis even though he doesn't give up TDs and breaks up passes all day.  Some people never learn.

Burn Ratio - Who's Not?

  • As a Jets fan, this doesn't surprise me as Buster Skrine had an up and down stint in NY.
  • He may not a household name (yet) like Jason McCourty but Charvarius Ward may soon be once OCs figure out why they are not throwing at him (and McCourty) more given their Burnability. 

Qualifier Rankings

Here are the qualifying corners ranked based on average of the four scores. 

  • The top names are no surprise. Here they are with their Week 12 opponents:
    •  Ryan (@CIN with backup QB Ryan Finley)
    • White (vs LAC with rookie sensation Justin Herbert)
    • Callahan (hosting Taysom Hill and NO)
    • Bradberry (see Ryan above)
    • Fuller (@GNB Sunday night)
  • Here are the guys making up the bottom of the list:
    • Oliver (hosting Derek Carr and LVR)
    • Murphy-Bunting (hosting Machines and Co.)
    • Skrine (see Fuller above)
    • Gladney (hosting CAR with Teddy Bridgewater set to return)
    • Flowers (visiting PHI Monday night)
    • Okudah - played Thanksgiving with the result being Deshaun Watson lighting the Lions up for 318 yards and 4 TDs with no INTs. Oh, and the head coach getting fired.

Will post updated info from Week 12 later in the week.
