Since his sophomore season, Knox had started at both defensive end and tight end for Concord (N.C.). This past season, though, the 6-foot-1, 231-pounder focused almost exclusively on offense, with the exception of the final game.
The shift in focus contributed to an improvement in Knox's route running and blocking.
"I became a lot more aggressive (as a) blocker and my route running has become a lot more crisp," Knox said. "So I caught more balls this year."
On the season, Knox caught 32 passes for 426 yards and seven touchdowns, improving his reception and yards numbers from the previous season (14 catches for 253 yards and eight scores). He also had two pancake blocks.
Having to fill in for a suspended defensive starter, Knox started both ways in Concord's third round playoff loss to Mount Ulla (N.C.) West Rowan. Knox had four tackles as Concord lost, 20-14.
"I was really happy to play some defense, but we lost," Knox said. "There was really terrible officiating in that game – we didn't get any calls in that game [and] West Rowan got all the calls, probably because they were home. And then we didn't execute any important plays that would have allowed us to win."
Despite the playoff exit, Knox was pleased by Concord's season, which ended with a 10-4 record.
"It went really well, because we only had two returning starters [coming into the season] – we had a really deep senior class," Knox said. "We were preseason picked sixth in our conference and we ended up finishing second and competing for the championship. And we made it to the third round [of the playoffs]. We really exceeded a lot of people's expectations."
With his football season over, Knox will now enjoy his final few weeks before graduating from Concord on Dec. 21.
"Everything is all set to go," Knox said regarding his early graduation. "I've filled out all my paperwork, got my grades where they need to be, got my SAT score – I'm all set."
Approaching the end of his high school days, Knox has a bittersweet feeling.
"High School has been a great time in my life," Knox said. "But it's time to move on."
A mid-October official visit to UNC finalized Knox's next step – enrolling at UNC in January.
"My decision is solid," Knox said. "I'd strongly doubt anything will change with me."
One reason for his strong position in spite of the uncertainty that surrounds UNC is that Knox, who hasn't planned and isn't considering any future recruiting trips, has accepted the possible outcomes.
"I think the coaching change is probably going to happen," Knox said. "The new AD has stepped in and there's probably going to be a coaching change. I just have to roll with the punches.
"I might start second guessing if they get rid of [Allen Mogridge], because I've built a strong relationship with him and it would be hard to see him go. But for now, I'm a Tar Heel."
