Paul played much of the year through back pain, which ultimately ended his season early, and NFL followers have been disapproving of a two-sack season.
"I've got something to prove this year, and I want to shut them up," Pierre-Paul told The New York Times, according to the official NFL website.
"A lot of people are doubting me. I know what people have been saying. But it's okay; I'll get them back this year."
Paul is now into the final year of his rookie contract at the Giants.
