The Raiders' struggles last season were well-documented. In his first year back at the helm of the Silver and Black, Jon Gruden's club struggled to rush the passer, stop the run, extend drives and score points en route to a 4-12 season. Following that disappointment, Gruden and general manager Mike Mayock remade the roster, adding star power in Antonio Brown, reliability in Tyrell Williams and Lamarcus Joyner and potential in a rookie class that includes three players who starred at Clemson.
