Obviously, it would be a terrific pick-up.
I look at the team as needing 3 main positional areas: OL, DT, and S.
I think we need to come away from free agency with at least 1 good to very good player in one of those 3 areas. If we got Byrd, then we could focus on OL and DT in the first 2 or 3 rounds of the draft.
Needing all 3 will be more than we can do in just the draft alone, IMO, unless we get very lucky with a later round pick.
If we can't get Byrd from Buffalo, then we need to get Levitre for guard. Make the Bills choose who they want to lose.
