Anything you can do I can do better: Arizona's Peterson intercepts a pass.
NFL cornerbacks are very sensitive and love to argue on Twitter.
The latest round of back-and-forth bickering comes from Arizona's Patrick Peterson and Seattle's Richard Sherman (of course).
This particular dustup was started by Peterson on Thursday when he knocked Sherman during an interview with Arizona Sports 98.7 FM.
"A lot of guys say he's a shutdown corner," Peterson said. "But if you look at film and guys who understand the game, go back and look at film and see how his defense is. I believe that if you put him in our system, I don't believe he'll be able to last, honestly. Because I actually do much more than he is [doing]."
You knew Sherman would respond — and he did, via Twitter.

Peterson then came back with photographic evidence to back up his point.

That's what I always see someone helping. Last I check a lockdown corner is when it's him and WR.

@RealPeterson21 wideouts regularly have career days on u. They ask u to stop them. Not let them score at will.

Peterson then used more than 140 characters to make his next point.
