'The price isn't crazy for Groy, who filled in admirably for the Bills at center after Eric Wood broke his leg. Groy started seven games and proved to be a solid option. With Wood entering the final year of his contract, and guard Richie Incognito getting older, depth is crucial for the Bills on the interior of the offensive line. With Groy and the signing of Vlad Ducasse, the Bills have plenty of depth on the offensive line, although right tackle is still a weakness.'
