George Selvie sat on a stool yesterday eight lockers down from the one being occupied by Giants defensive end Jason Pierre-Paul. Four years ago, Selvie and the man now known as JPP shared another locker room, the one at the University of South Florida, where the two were teammates dreaming of riches in the NFL.

Pierre-Paul has earned his measure of success winning a Super Bowl and reaching a Pro Bowl. Selvie, meanwhile, is trying to prove he can play on Sundays and avoid a legacy of unfulfilled promise. The 6-foot-4, 270-pound defensive end is part of a group of free agents signed by the Giants participating in a mini-camp this weekend with rookies.

“Those were good times,” Selvie, 26, said yesterday about his days playing with JPP and the Bulls. “We had two good defensive ends behind us and we were winning games. We had a good time in South Florida back then.”

Back then, Selvie looked like a can’t-miss prospect in the NFL. He played at South Florida from 2006-09. He was a consensus All-American and the Big East Defensive player of the year in 2007, when he collected 14.5 sacks. But his numbers tailed off; he had 5.5 sacks in 2008 and 3.5 in 2009, the year JPP joined the Bulls and collected 6.5 sacks.

“You could see he was raw, but you couldn’t touch his athleticism,” Selvie said of Pierre-Paul. “He had speed and size.”

JPP has blossomed into a star. Selvie is looking for a job. After being selected by the Rams in the seventh round of the 2010 draft, Selvie played one season in St. Louis before being released. He was with the Panthers early in 2011 before joining the Jaguars, with whom he finished out 2011 and played all of 2012.

It appeared he was headed for a fresh start when he signed with the Buccaneers last month just before the draft, but he was released on Monday. He has just three sacks in his pro career.
