But the Bills still found a way to do things that were unexpected.
The release of Brown brings the Bills' roster down to 53 players after the team also reportedly cut running back Jonathan Williams and linebacker Gerald Hodges.
Williams was expected to play a significant role behind LeSean McCoy in the Bills' backfield after Mike Gillislee signed a restricted free-agent deal with the New England Patriots in the offseason. Williams was drafted past year out of Arkansas and appeared to be a promising talent. He rushed 27 times for 94 yards and one touchdown. Those numbers will obviously change, depending on where the 23-year-old lands.
Releasing the 6-foot, 223-pound running back leaves former Raiders back Taiwan Jones, with 183 rushing yards in six seasons, and fifth-year veteran Joe Banyard, who has 95 career rushing yards, as McCoy's backups. Williams averaged 5.8 yards per carry during the preseason.
The moves are making room for the players the team are adding from cuts made by other National Football League teams.
Buffalo continued to tinker with their roster Sunday as they were awarded claims for three players, LB Deon Lacey, TE Khari Lee and OT Conor McDermott.
McDermott comes to the Bills via New England, while Lacey and Lee come to Buffalo from Miami and Detroit, respectively.
