In spite of that, Knox hasn't completely ruled out the possibility of visiting other schools.
"I'm kind of in-between," Knox said. "But I'm keeping my options open. UNC still has to face the NCAA in October. You never know, UNC could get hit down with the hammer. [If that happens], I don't want to be like ‘What now?'"
Knox doesn't have any visits in mind – outside of UNC games. He plans to be in Kenan Stadium for the Tar Heels' season opener against James Madison on Sept. 3 and the game against Miami on Oct. 15. He's also considering being on hand when the Tar Heels host Louisville.
Outside coaching staffs haven't passed on the opportunity to pursue Knox.
"In light in particular of what has happened there, there are a lot of people that are pressing hard for him to look at his commitment and try to make him waver on it," Concord head coach Glen Padgett said.
During Saturday's visit to UNC, Knox had several conversations with Allen Mogridge, his primary recruiter and the Tar Heels' tight ends coach.
"He said, ‘Carolina is still Carolina with or without Butch Davis,' and that they are still going to do great things this season and they expect a lot out of the players they have because of the talent that they have" Knox said.
Also on Saturday, Knox had his first meeting with Everett Withers. The two spoke individually in Withers' office.
"We were just talking," Knox said. "He's a great guy. He's more like a father figure now. I believe in him and he believes in the football program at North Carolina. He was just reassuring me that it's still Carolina – just like Coach Mo' said."
In UNC's pro-style offense, Knox is an ideal H-back.
"[Knox's] has an excellent work ethic, he's a good blocker, he's a good receiver – he's what that style offense looks for in [the H-back] position," Padgett said.
Knox also has experience playing the H-back position in Concord's spread offense.
"He plays H-back in our one-back double-tight stuff, because we feel he catches the ball well out of the backfield, he does a good job of sealing the backside, [and] he does a good job of blocking the edge," Padgett said.
With only four total starters returning, Concord will lean heavily on Knox this coming season – especially on offense.
"I think one of the advantages with [Knox] particularly on offense is he's an extra lineman when it comes to blocking, but he's also an outstanding receiver," Padgett said. "Play-action wise, red zone wise – there's a lot of things he affords us the opportunity to do, because he can catch the ball and he's very good at setting the edge when it comes to ‘C' and ‘D' gap run plays."
Early in the season, Knox will see a select number of snaps at defensive end. But as the season progresses, his reps on defense will increase.
"On defense, he's very strong, but he's also very athletic," Padgett said.
