but if you wanna take a look at quality fairly recent QB's who were derailed early by knee injuries Culpepper would certainly qualify.

Carson was never really the same after his knee got crunched on the second play of the game in Pittsburgh during the playoffs, tho he did have a shoulder issue later too.

Donovan never made another Pro-Bowl outside of being an alternate-to-the-alternate in '08 after blowing out his knee in '06.

Bottom line, it's a shame but it's not a good sign.

Particularly when you've already done it before in college.
