EAST RUTHERFORD, N.J. -- New York Giants defensive end Jason Pierre-Paul says he feels in the best shape of his life, and is eager to show people that he is even better than the player he was in 2011, when he posted a career-high 16.5 sacks.

JPP, as he is known, struggled through a disappointing 2013 season after undergoing back surgery and then being relegated to injured reserve with a shoulder injury.

"I got something to prove this year, and I'm going to shut a whole bunch of people up," he said. "I want to shut them up, you know what I'm saying? It's not even going to be new to me.

Pierre-Paul said on occasion he will "feel a little something," but he doesn't believe it will affect him on the field.

"At the end of the day, it's nothing that is going to bother me while I'm playing," he said.

"Now, I'm flying to the ball. Last year (due to back surgery), you couldn't expect me to come in and do what I did in (2011) -- then I got hurt with my shoulder."

The good news is Pierre-Paul is over that shoulder injury as well, which is why he's readying himself for a big year.

"I'm confident in the way I play my game, you know what I'm saying? When I'm at the top of my game, it's ridiculous. Everyone has seen me there before."
