Patriots cornerback Kyle Arrington with an interception against the Dallas Cowboys.A starter for the final 15 games last season, Patriots cornerback Kyle Arrington may have started the 2011 season in a reserve role, but he's emerged as the team's best cover man at the midpoint of the year.

Beyond his team-high five interceptions, Arrington has limited opponents to 21 catches for 311 yards over 47 targets, according to stats logged by analytical site Pro Football Focus. Opposing quarterbacks boast a mere 41.5 rating when throwing in Arrington's direction.

Entering Week 10, Arrington had the fifth lowest completion percentage in the league among cornerbacks that had played at least 50 percent of their team's defensive snaps. Only the New York Jets’ Darrelle Revis (44 targets, 15 receptions, 34.1 percent), Pittsburgh’s Ike Taylor (58, 20, 34.5), Carolina’s Chris Gamble (30, 11, 36.7) and Philadelphia’s Asante Samuel (47, 21, 42.9) ranked ahead of him. What’s more, Arrington ranked third in QB rating, with only Revis (18.3) and Gamble (33.1) ahead of him.
