ESPN.com is reporting that the Bills have sent RB Willis McGahee to Baltimore for three draft picks. Buffalo will receive the Ravens’ third and seventh-round picks this year, as well as a third-round selection in 2008.

Baltimore needed to make a move for a back because Jamal Lewis signed a one-year deal with Cleveland on Wednesday. McGahee joins a crowded backfield that includes Musa Smith and former Bronco Mike Anderson, but presumably will be the starter.

The interesting thing now is whom Buffalo will go with. The Bills will soon bring in Dominic Rhodes for a meeting, but will have to compete with Tennessee for the former Colt. Another developing situation is in Green Bay, where the Packers are in need of a halfback after Ahman Green jettisoned to Houston. If Buffalo can land Rhodes, than Green Bay might have an easier time landing California RB Marshawn Lynch in the first round of next month’s draft.
