Which Teams Have the Best Corner Units?

July 16, 2008

In part four of the series assessing cornerbacks using K.C. Joyner’s YPA stats from 2004 through 2007, I move from individual assessments to unit ratings. Joyner has a new set of ratings in Scientific Football 2008. I’m not going to rely on these numbers, though I will relay that Dallas finished ‘07 in the top ten.

I’ve chosen to overlook his ‘07 ratings for two reasons. First, they’re exclusive to 2007. Joyner rates the corner units as they performed in ‘07. That’s fine, but with Adam Jones joining the Cowboys’ roster, fans are interested in predictive stats.

For that reason I’m using any and all of Joyner’s numbers from the past four years. I figure more is better. As you’ve seen, a player’s YPA’s can fluctuate wildly from year to year. If we want an idea of how a corner is likely to perform in ‘08, I think it’s best to use all the data that’s available. In Terence Newman’s and Anthony Henry’s cases, I’m using their four-year averages, since those numbers are available. In Jones’ case, Joyner has two years of numbers on him, so I’ll go with their average and will do the same with every other CB.

I’m also rating the units three deep, since nickel backs are vital in this era of spread sets. This will lead to some omissions that cannot be helped. For example, Buffalo will be playing a rookie, Leodis McKelvin at one corner spot this year, so I can’t put a number on his performance.

Lastly, I’m simply averaging the three player’s YPAs here, which does not give proper weight to each player’s contribution, so consider these “soft” averages. Therefore, I’m going to place the units in tiers, rather than in a column. By coincidence, there are only five units that have an average YPA below 7.0, so they form my pantheon. Here they are in alphabetical order, with each player’s average YPA in parentheses:

1. ChicagoNathan Vasher (5.7), Charles Tillman (6.6), Trumaine McBride (7.1)
Vasher is the best corner we have not discussed yet, because I have not rated players with only two seasons of YPAs. Vasher was top notch in ‘05 and ‘06 but missed 12 games last year because of injury. McBride filled in and posted a very respectable 7.1 YPA.

2. DallasTerence Newman (6.2), Adam Jones (6.3), Anthony Henry (7.4)
Jones has an average near Newman’s and has a career peak topping Newman’s, posting an outstanding 5.4 YPA in ‘06. (Newman’s career best is 5.7.) If Jones can approach this number again, he’ll be a starter.

3. Green BayCharles Woodson (6.5), Al Harris (7.5), Jarrett Bush (6.6)
Harris gets a lot of love from the press, but his YPA is lower than Anthony Henry’s. Like Henry, he’ll break up passes but give up some huge gains. Bush was very good in his first year at nickelback.

4. PittsburghDeshea Townsend (6.3), Ike Taylor (7.4), Bryant McFadden (6.0)
It’s feast or famine with this bunch. Taylor has been consistently average at one corner and therefore draws most of the action. Townsend and McFadden have alternated so-so seasons with off-the-charts good ones. Both had YPAs below 5.5 last year. If the pattern holds, they’ll be off this season.

5. WashingtonShawn Springs (5.5), Fred Smoot (6.8), Carlos Rogers (7.1)
Springs outstanding play the past four years raises this bunch, but Smoot and Rogers have been steady and good, if unspectacular.
