Kyle Arrington, 28, has been the Patriots' top slot cornerback for the past five seasons. His value was on display in January's AFC Championship Game, when he held Colts star T.Y. Hilton to one catch for 36 yards in a blowout win. Arrington finished 36th out of 108 qualified corners in Pro Football Focus' ratings. In 2011, he led the NFL with seven interceptions. We need to pick him up fast, he's prettty cheap.
