Doug Whaley's not done wheeling and dealing.
The Buffalo Bills' general manager agreed to his second trade in as many days Wednesday, this one with the Minnesota Vikings for veteran quarterback Matt Cassel.
That comes a day after the Bills agreed to send linebacker Kiko Alonso to the Philadelphia Eagles in exchange for running back LeSean McCoy.
To acquire Cassel, the Bills will send "undisclosed draft choices" to Minnesota in exchange for the quarterback and an "undisclosed draft choice."
Both trades can not be made official until the start of the 2015 league year, which comes at 4 p.m. Tuesday.
Cassel, 32, is entering his 11th NFL season. He has played for New England, Kansas City and Minnesota. He started the first three games of 2014 for the Vikings -- going 41 of 71 (57.7 completion percentage) for 425 yards, three touchdowns and four interceptions -- before a broken foot ended his season.
Cassel provides the Bills with a veteran to compete with third-year pro EJ Manuel for the starting job. A 6-foot-4, 228-pounder, Cassel started his career as a backup to Tom Brady with the Patriots.
When Brady was hurt in the 2008 season opener, Cassel got his first extended playing time, going 10-5 as a starter and leading the Patriots to an 11-5 record (although they still missed the playoffs). Cassel went 327 of 516 (63.4 completion percentage) that season for 3,693 yards, 21 touchdowns and 11 interceptions.
He played so well that the Patriots used their franchise tag on him, which would have guaranteed him a one-year salary of $14.65 million. Cassel never signed that, however, and was traded to Kansas City for a second-round draft pick.
The Chiefs signed him to a six-year contract worth up to $63 million. He played four years of that deal -- earning $46 million -- before being released after the 2012 season. In four years with the Chiefs, he started 47 of 48 games he played, throwing for 9,549 yards, 59 touchdowns and 44 interceptions. He led Kansas City to the playoffs in 2010, when he threw for 3,116 yards, 27 touchdowns and just seven interceptions.
Cassel has one year left on his contract and will earn $4.75 million from the Bills in 2015. When he and McCoy are officially added to the roster next week, the Bills will have $12.833 million of salary cap space.
