Denman is working with a trainer to bulk up and arrive at Rutgers in the best shape possible to compete for time at guard.
"I think he's been working pretty hard," said Pennsbury head coach Galen Snyder. "He's very focused. I saw him the other day. He's been working out all the time. He's probably up to about 320. He's carrying it well."
Denman had committed to both Penn State and Wisconsin before finally deciding on Rutgers after a January official visit. Sticking with the Scarlet Knights through a coaching change, Denman has been gung ho about his future team, Snyder said.
"I haven't had a lot of talks with [the new staff], but I have heard all good things about them from J.J.," Snyder said. "Both (position coach Damian Wroblewski) and the head coach (Kyle Flood) as well are offensive line guys, so it's great for him. I've heard all positives. I think it will work out fine."
Snyder sees Denman as someone that will be able to contribute to the Rutgers offensive line based on his road-grader attitude and athleticism at the position, but does not want to speculate on when his former star will be ready to play.
"I don't really know, with the kids they have, what he would look like," Snyder said. "I think either way, he's set for a good career at Rutgers. The coaches will see where he is when he gets there and I think he could play if that's what they want.
"They're getting a kid who has size and athleticism to be a real force on an offensive line in college football. It's really that simple with J.J."
Denman is one of four Scarlet Knights playing for the Pennsylvania squad in the Big 33 this year. He joins Archbishop Wood (Warminster, Pa.) players Desmon Peoples and Brandon Arcidiacono and Bloomsburg (Pa.) Area quarterback Blake Rankin.
"You're proud of all of your kids that do well," Snyder said. "They move on and help make a name for this high school. He'll do great at Rutgers and the Big 33."
For Snyder and the rest of Pennsbury, Denman will be sorely missed on the field and off the field.
"He gave you a presence on the offensive line that's hard to duplicate," Snyder said. "He did a really solid job for us for three seasons. You're not going to really replace him, but you're going to do the best that you can and we'll be OK. We're certainly going to miss him though."
