I want to say Stevie Johnson, I'm not an insider by any stretch of the imagination but I heard he had one of his best weeks of practice, the Bills are now starting to look down field to make a plays a little more, a lot of eyes are on Stevie this week he will perform and I believe he might have a 10 catch ,100 yard 2 td kind of day....
But imma go with Dareus, he has become a vocal leader in the locker room, and after a quite game last week due to some sickness and alot mangol,I see him being very disruptive throughout the game and it doesn't hurt that the Bills are now play more 4-3 and 5-2 defensive schemes(switch I believe at dt he can thrive in ) Big Day..... 2 sacks....5 tackle ....1tkl...(he will spark the whole defense)
