Bernard was a big question mark for fans and people (including me) were pretty upset that the Bills did nothing at the linebacker position. I guess the easy place to look is WR.
But guy who was here last year, didn't do much but is expected to have an expanded role? My answer would be David Edwards. I think a lot of fans have questions about McGovern moving to center (I do not). And although the Bills have added IOL since the Morse cut, I do think Edwards will surprise a bit and be really good.
I do think there is a chance Van Parn Granger makes some noise here, but Edwards was really, really good in LA,a super bowl winner, and he looked like a guy who was going to get a huge extension or free-agent contract when he got there until he had all the injury issues in that last year with LA. I think Edwards is going to be a rock on the offensive line this year.
