Check here for a full list of roster moves.
Biggest surprise: Many believed the Bills could keep an extra running back, either veteran Chad Simpson or undrafted rookie Joique Bell, because Marshawn Lynch and Fred Jackson have been banged up. Simpson and Bell had strong summers, but the Bills cut them both. It's also notable the Bills have given up on 2008 second-round pick James Hardy. The 6-foot-5, 220-pound target never looked as good in action as he did in a uniform. He had injury problems, missing almost all of last year while recovering from a knee injury. He had sports hernia surgery in the offseason. Undrafted rookies outperformed him in camp.
No-brainers: There was no reason to keep rookie quarterback Levi Brown on the 53-man roster. He was drafted in the seventh round out of Troy as a long-term project. He's a safe bet to clear waivers and be added to the practice squad, but if another team snags him, no big loss. The move means the Bills likely will keep backups Ryan Fitzpatrick and Brian Brohm, each of whom started for them last year.
What's next: On a team that hasn't made the playoffs in 10 years, few positions should be safe. That fact is emphasized by the number of undrafted rookies who made the squad. Bills general manager Buddy Nix will monitor the waiver wire and scrutinize all the veterans who've been dumped into the free-agent pool to see if there are any fits. The Bills will try to improve their offensive line depth and defensive front seven, especially.
