Id be happy with either:
Kiper: Jake Matthews
Analysis: The injuries to EJ Manuel last season would make you think pass-blocking has to be a priority, but where the Bills' offensive line was really bad was in creating any push in the run game. You don't just protect a young QB by creating a pretty pocket, it's also nice when he can hand the ball off with any reasonable sense of optimism. Matthews will help. I suspect he'd jump in right away at right tackle and succeed -- he can play left or right -- and his ability to finish as a run-blocker could pay early dividends.
McShay: Sammy Watkins
Analysis: The Bills have more pressing needs than wide receiver, including offensive line (specifically guard and right tackle), tight end (if Scott Chandler is not re-signed) and safety (if Jairus Byrd is not re-signed), but pairing young and developing QB EJ Manuel with the top receiver in this year's class might be too tempting to pass up. Watkins is a physical receiver with a big-time second gear who is very competitive when the ball is in the air. Texas A&M's Mike Evans would also make a lot of sense, as his size would provide a good complement to the smaller, faster receivers on Buffalo's roster.
