Both on his body and his mind.
Webb, a four-star defensive tackle at Timber Creek Regional High and a North Carolina commitment, is still a few weeks from being cleared to play, and watching the Chargers get off to a 2-2 start has been painful.
"It's one of the worst things I've ever felt," Webb said. "The ACL is nothing. It's the afterwards part of it."
The "afterwards part" is broken into frustration about the slow-moving process of ACL rehabilitation and not being able to anchor the defensive line for the defending South Jersey Group III champs.
The 6-foot-1, 300-pounder was presented with his jersey for the Jan. 5 U.S. Army All-American Bowl in San Antonio on Monday, but his focus is on getting back on the field.
"I'm doing a lot of running, lateral movements, working on my backpedaling so my hamstrings are strong," Webb said. "I'm doing a lot of conditioning work and getting ready."
The plan is for Webb to return either late this month or in early November and help Timber Creek push toward the playoffs. It's a much different role than the one he currently employs.
"I'm just a sideline cheering guy, and I help out some of the guys and show them what I know," Webb said. "If I can help in any way, I do. I try to be a support system on the sideline. I'm just another cheerleader with a little more advice."
One thing Webb isn't concerned about is his future.
He changed his commitment from Penn State to North Carolina over the summer when he and teammate Dajaun Drennon, a four-star defensive end, both visited Chapel Hill and chose the Tar Heels.
They are planning official visits in January, and Webb said he is excited to play the 3-technique in North Carolina's defense.
"I liked the way I'll be set up there and the way I can play, and the success I can have at my position," Webb said. "The way they have (the 3-technique play) is at the central part of the team. He's at the forefront and he makes most of the plays."
Although Webb has yet to visit for a game this season, he is keeping a close eye on the Tar Heels.
"It feels good to watch something I know I'm going to be a part of next year," he said. "That means I'm going to be there next year having fun."
