I'm not sure I see the point in these statistics? Teams don't pass at Asomugha for several reasons.
- He's a top corner.
- They're usually winning by a wide margin, and pass less frequently.
- The other side of the field featured Fabian Washington in 2007, and DeAngelo Hall (mostly) in 2008.
He wasn't thrown at much in 2007 either, but the YPA when throwing at him (7.0) was only good enough to place him 30th in the league. Last year, with the 29 times he was thrown at (which you mentioned incorrectly as 27) the YPA was only 4.97, a drastic improvement. Still, several players fared better. Corey Webster (66 attempts, 3.92), Richard Marshall (39, 4.51), Mike Jenkins (38, 4.34), Darrelle Revis (72, 4.96), Sheldon Brown (63, 4.84), Samari Rolle (44, 4.07) and Brandon Flowers (66, 4.83). Those players were all thrown at more frequently, of course, but this DOES provide a better sample size.
Oh, and keep in mind the "thrown at" categories can get a little sketchy when zones are involved. So, throw the attempts, YPA, and all that out the window.
Showing single categories, or lumped categories all displaying basically the same stat, can be used to show just about anything you want.
Heck, according to the most comprehensive 'stat' I've seen.. William Gay was the best corner in the league last year -- and Stanford Routt was #10!
I'd really like to see a nice, easy metric for corners that includes everything. Wishful thinking, I guess.
