I disagree.
I thought just before he was hurt he started coming on and playing well.
And just the fact that he has gone through the whole first season, training camp, and all the in's and out's of being in the NFL give a 2nd year guy an edge he didn't have coming in as a rookie.
Are the Bills counting on him? I suppose that is hard to say. I think if the Bills add a wide body DT, McCargo is going to fit into the Bills Defensive line philosophy of speed and lots of rotations very well.
Yes he needs to prove that he can stay healthy, but that isn't something you can predict one way or another.
