Cardinals acquired CB Javier Arenas from the Chiefs in exchange for FB Anthony Sherman.
A nickel corner, Arenas was expected to be a return ace when the Chiefs made him the No. 50 pick of the 2010 draft, but he's proven to be highly ordinary on special teams. He'll be a candidate to man the slot in Arizona, but the presence of Patrick Peterson and rookie Tyrann Mathieu means Arenas won't be featured on returns. Arenas played a career-high 724 snaps last season, but graded out as the No. 51 corner in Pro Football Focus' ratings. The Cards have now added Arenas, Antoine Cason and Jerraud Powers at cornerback. Mathieu will play safety, but could eventually see time in the slot.
