Webb, who stars at Timber Creek Regional High (Erial, N.J.), committed to Penn State on Thursday afternoon.
"He called coach (Bill) O'Brien half an hour ago and committed," Timber Creek coach Rob Hinson said midafternon.
Webb's decision comes a few months after he had all but written Penn State off after being ignored at a game by the former staff.
However, O'Brien and his staff rebuilt the relationship, and when Webb was on campus last month he talked about his affection for Penn State, and how the past was remedied.
He also got to know the staff well, and likes how he will fit into Penn State's defense.
"They were just talking about how they would use me and how I would benefit Penn State," Webb said after that visit. "I'd be playing the 1- or the 3-technique."
At the time, Webb also liked what he learned away from football on the visit.
"I feel like it's legendary, and a lot of people feel the same way about it," he said then. "I feel like it's just a great place to be and an environment that is healthy for a student to succeed because everything is around you already."
