In Hakeem Nicks and Victor Cruz, the New York Giants have two of the NFL's best at getting yards after the catch.
If Kyle Arrington can't prevent the ball from getting into their hands in the first place, he needs to be able to bring them down before they're off picking up giant chunks of yardarge.
Nicks and Cruz have 18 and 17 receptions this postseason so far, which puts them at second and third, respectively, among pass-catchers.
In the New England Patriots' bend-but-don't-break defense, tackling is key, and that is what Arrington will have to do to make stops or at least prevent touchdowns.
In the Pats' week nine matchup against the Giants, Arrington only had two tackles. It's good for corners to keep their tackling numbers low, provided that it's because they aren't allowing catches to be made by the receivers they are covering.
But the Giants' offense is red-hot right now, and Eli Manning will not have much trouble completing passes against the Patriots' defense. Arrington's tackling numbers will have to increase on Sunday if he wants to win his first Super Bowl.
