Raiders signed CB Carlos Rogers, formerly of the 49ers. Rogers, 33 in July, was released by the 49ers three weeks ago. His visit to Oakland on Monday was his only one. Rogers can still play as a slot corner who can defend the run a bit and will fill that role for the Silver and Black. Tarell Brown and D.J. Hayden will serve as the outside corners. The Raiders are loading up on aging veterans in an attempt to compete in the tough AFC West in 2014.
