Buffalo's Record in 01' : 3-13 (pre Bledsoe)
Buffalo's Record in 02' : 8-8 (with a horrible defense and Bledsoe shattering all of Jim Kelly and the Kgun's franchise records)
Buffalo's Record in 03': 6-10 (started 2-0, but after Donablow got rid of 75% of Drew's weapons the offense went into a tailspin and yes Drew looked very bad at times)
Buffalo's Record in 04': 9-7 (started 1-5 and 3-6, then Bledstud led the team to victory in 6 straight MUST WIN games before the Bills vaunted defense let the steelers scrubs mandhandle them)
Buffalo's Record in 05: 5-11 (post Bledsoe)
*also keep in mind Buffalo has had one of the worst offensive line's in the NFL the past 6 years.
Now....
Dallas's Record in 04: 6-10 (pre Bledsoe with the great Vinnie Testeverde who people feel the need to compare Drew to)
Dallas's Record in 05: 9-7 (barely missing the playoffs and division title with Bledstud at the helm)
I won't bother posting the Pats stats, but they were the laughing stock of the AFC before Drew was drafted, and we all know what happened after Drew left....that's another debate as to if Drew would have had the same success that Brady had.
Bottom line, keep believing that Drew isn't a star and that these teams had other superstars to lead them. The records speak for themself and it's no correlation that the number of wins seem to higher with Bledsoe on the team than without him.
