This is a false argument. I don't see San Francisco or Seattle, teams stocked with talent, releasing top players to sign other ones. Why not? The Bills are $20m under the salary cap. They had plenty of room to sign Levitre, Byrd AND Spiller next season.
Really? Are you going to list Urbik and Pears too? They were re-signed. These guys are not the same as Levitre or Byrd. Those are the guys you CUT to sign top guys like Levitre and Byrd.
