Patrick Peterson has just become the highest cornerback to ever play the game after signing a five-year, $70 million deal extension with the St. Louis Cardinals. And apparently, he believes his rival, Seattle Seahawks cornerback Richard Sherman, is not happy about it at all.

The Cardinals granted what Peterson has been asking all along - a contract that would allow him to surpass Sherman's four-year $57.4 million contract extension last May.

It was a smack on the face for Sherman, who has been feuding - at least on Twitter - with Peterson for quite some time.

On the other hand, Peterson considers his word war with Sherman not that personal, though he believes the Seahawks cornerback is thinking the other way around.

"I don't know how he feels about but I think it's just fun, healthy competition," Peterson said. "I'm having fun with it. Sometimes it seems like he's a little salty about it. But it is what it is. I don't have any problems with Richard. I don't have any beef with him. I'm having fun. I don't know if he's having fun."

Peterson, who recorded 42 tackles with three interceptions last season for the Cardinals, believed the landmark contract for cornerbacks is important for his confidence as he looks to produce big numbers next season.

"I think it's just going to make me take my game to the next level," Peterson told ESPN. "Obviously, we had our exchanges over the last month or so -- obviously he's still exchanging words this morning. But like I said, it is what it is.

The Cards cornerback added that he has no ill feeling towards Sherman, but he believes his feud with him could generate tremendous buzz every time the Cards and Seahawks go head-to-head next season, particularly on TV ratings.

"I have no harsh feelings toward Richard, I wish him the best of luck throughout his career, throughout his season. I guess it'll be much-watch TV when we play Seattle," Peterson added,
