The last few seasons Iíve put together articles ranking CB production based on a simple formula I developed tracking their pass defensive skills. This article tracks the most productive Corners through the mid-point of the season.
Here is what I used in my formula: Interceptions, deflections and catches allowed. I decided not to use tackles, sacks etc because, one, they aren't the CBs main duties, and two, they seem more the result of scheme and other players on the field (for example, a CB may have a lot of tackles, but it could be because the front seven are very bad).
To easily get the raw numbers below, I simply multiplied INTs x 2, added that number to the total deflections (reasoning an INT was twice as good as a deflection). Then I divided the total catches allowed by the INT/deflection number.
So for example, if someone has 5 INTs, 20 deflections and 30 catches allowed, I added 10 (5 INTs x 2) + 20 and divided 30 by 30, coming up with a score of 1.00. The lower the score the better.
To qualify, I normally look at players with at least 20 pass deflections or 20 catches allowed. Since weíre around the mid-point of the season, that number is 10 pass deflections or 10 catches allowed. Iíve tweaked this over the years, but I feel like this captures most, if not all, of those who should qualify. In total, I ranked 72 CBs, which is in line with the average number I look at towards the end of the year. Last year, for example, at the mid-point I ranked 73 CBs.
Some interesting notes on the rankings. Last yearís highest ranked CB, Sam Price from Pittsburgh tumbles all the way to 49th. Only one player from last yearís Top 10 is back in the top this season, Richard Sherman who is 5th this year after ranking 9th last season. Kansas City CB Marquis Robinson is 11th this year after coming in 5th last year.
Usually, at least one team puts two CBs in the Top 10. However, this is not the case this year. However, the Packers have the 12th and 13th best in Cobrani Rogers and Dee Wagner. Whatís interesting is how many of the Top 10 are young and highly drafted. Six of the Top CBs are 25 or younger and 8 of the CBs were taking in the first 12 slots of the draft. All were taken by the middle of the second round.
There were some high profile rookies taken at the position this year. Angel Rosario the first CB taken is ranked 18th overall, which is pretty impressive. Buford McKay, the 5th pick overall did not have enough playing time to qualify. Commodore Bell, the 9th pick overall comes in at 35th overall. The next CB taken, Emerson Dupree ranks a little higher at 23rd. Rookie Hunter Hill who went 11th is the highest performing so far, ranked 10th overall. Marcus Peters, the only other CB taken in the first did not qualify.
The worst CB who qualified? Itís a tie between Sanders Commings of Baltimore and Antonio Smith of Washington. Both have zero picks, 1 deflection and 10 catches allowed for an efficiency rating of 10.000.
Hereís the top 10:
1. David Amerson, MIN (CB Efficiency Ratio of .400)
2. Jimmy Smith, CHI (.500)
3. Camden Pietarila, DAL (.588)
4. Eric Victorino, BAL (.619)
5. Richard Sherman, SD (.722)
6. Trae Waynes, IND (.765)
7. Ray Turner, DET (.857)
8T. Demarius Stonewall, WAS (.867)
8T. Alan Morris, CAR (.867)
10. Hunter Hill, SF (.895)
