Given that signing Mario Williams significantly improves the Bills' defense, he's still one player and the defensive upgrade still needs a few more pieces. Then there is the offense, which while better than the defense last year, was still a work-in-progress. Given that the Bills also re-signed Stevie Johnson and a few other veteran FAs and that I don't expect them to make any more significant FA signings in 2012, here is my updated mock draft.

While I believe trading down in the first round is a definite possibility, I'm going to back away from that for now and just do a straight mock draft. I'm also editing my original draft. Finally, I'm assuming the Bills follow up the Mario Williams signing by also signing RDE Mark Anderson to complete the defensive front line makeover.

#10: OT Riley Reiff

#138: WR Ryan Broyles
#167: C Garth Gerhart
