I agree with musccy: Harris, Tauscher, and Driver.
Seems like Clifton is a little down this year. Favre could still qualify if he dramatically cuts down on the interceptions in the second half. And Henderson could make it on reputation, now that he's made it once already.
Those are the only six that are even close, with the possible exception of Nick Barnett.
Now the question of who actually WILL make it. Possibly none of them, because Green Bay is such a small media market and the team is having an off year. Harris is most deserving, but Favre and Driver have the best chance because they are higher profile.
