Walker, a 5-foot-11, 185-pound cornerback from Charlotte (N.C.) Mallard Creek, has been verbally committed to UNC since last March.
Prior to this step of signing his Letter of Intent, Walker completed another last part of the process less than a week ago when Larry Fedora made his in-home visit (head coaches are permitted just one in-home visit per recruit).
"We just talked about what my Signing Day was going to be like," Walker said. "We also talked about how it's going to be when I get there and what my goals are."
Goal No. 1 for Walker is earning immediate playing time.
"They said I could come in and contribute now," Walker said. "In my opinion, I think I just have to learn the playbook, learn the scheme, and get a feel for things."
Working in Walker's favor is UNC's need for pure shutdown cornerbacks, which happens to be Walker's forte.
"They told me they wanted me to guard [the opponent's] No. 1 or best receiver," Walker said. "I don't know if that's right away or after I get some playing time. I'm just going to see how practice goes with [UNC's] receivers and they'll base it off of that."
In the meantime, Walker is training for his collegiate career and running track for Mallard Creek. He participates in the 100- and 200-meter dashes, and the 4x100 and 4x200 relays.
"I think I'm faster than I was last year, for sure," Walker said. "Honestly, I think my core got better – I feel like I can finish out more races and be more durable throughout the season."
