JP Holtz played in 52 games over his four-year career at Pitt, and he was at tight end in every single one of them.

That might be where Holtz’s future lies if he gets an opportunity in the NFL, but the former Shaler standout, who worked out at Pitt’s Pro Day on Wednesday, said that there might be a different position waiting for him in the pros.

“Some teams asked if I’ll play fullback,” Holtz said Wednesday. I’ll do whatever a team needs me to do.”

Fullback would be a departure of sorts for Holtz. While his duties at Pitt often centered on being a blocking force for the Panthers’ run-heavy offense over the years, he almost always lined up on the line of scrimmage. Occasionally he would flex out to the slot or a receiver position, but tight end was his home.

With some NFL interest developing about his ability to play fullback, though, Holtz has had to show some different elements of his game this spring. So at Pitt’s Pro Day on Wednesday, he worked as a tight end and as a fullback.

“I feel good (in the fullback drills),” Holtz said after the workout. I’m willing to do whatever I need to do to make a team.”

Playing fullback might not automatically make him a lock for the NFL. A search on CBSsports.com’s database of NFL players showed just 30 in the league who are listed as fullbacks. And the Washington Times reported last fall that 10 NFL teams didn’t have a fullback listed on their rosters.

But adding positional versatility can’t hurt for Holtz as he looks for a way to latch on at the next level. He didn’t put up big numbers at Pitt - in four years, he caught 81 passes for 931 yards and 11 touchdowns - but he was a reliable presence, playing in every game of his career, starting 48 and missing just a handful of plays along the way.

Holtz tried to bring that work ethic to the Pro Day on Wednesday.

“I wanted to go hard in everything I did. I just wanted to prove that I can play. I feel like I’m a football player and I wanted to prove it.”

In terms of testing, Holtz checked in at 6’3” and 238 pounds. He did 20 reps on the bench press, leapt 33” in the vertical and had a 9’4” broad jump.
