Peterson might be NFL’s one true shutdown cornerThere are a few top-tier corners, but I have to go with Arizona’s Patrick Peterson. The sixth-year corner can play man coverage on any receiver and might be the only true shutdown corner in the league heading into 2016.Darrelle Revis hasn’t been dominant as of late, while Josh Norman and Richard Sherman are good route readers and great at playing zone. But I can’t justify any of these three being ranked ahead of Peterson right now.And finally, Charley Casserly singled out Peterson’s ability to make plays for whatever kind of defense a team employs.Peterson can fit into any defense — and he’s a threat to score after any pickI would go with Patrick Peterson. I think he is the most complete CB. He can press, play man coverage from an off position and can hold his own in a zone scheme. Also, he has the ability to make plays with the ball when gets it.Sherman was named by two of the panelists while Revis got the nomination from one.Peterson is coming off arguably the best season of his career. He was named a first-team All-Pro for a second time after collecting 35 total tackles along with two interceptions and 10 passes defensed. According to ProFootballFocus he allowed more than 50 yards in a game just twice in 2015, surrendering 56 to the Chicago Bears in Week 2 and 52 in the Divisional Round win over the Green Bay Packers.

When you combine pure coverage, ball skills, playmaking ability, smarts and versatility, nobody’s on his level.Peterson said he thinks he doesn’t get the credit because he doesn’t talk like the other corners. (Well, he talks at least a little bit. But that’s neither here nor there.)
