Since arriving at New Hanover, Walker, a 7-footer filled with potential, has made plenty of progress.
"I feel as though I've worked on my worth ethic and my leadership," said Walker. "I feel as though I've worked on my strength as well; thanks to Coach ‘Mot' [Kevin Motsinger]. Just going to the gym and working out, going to practice has gotten me better."
Strength, though, is still a clear area of weakness for Walker.
"I think I just need to keep working on my strength," said Walker. "That's the main thing everybody is telling me."
Walker will continue to work hard in New Hanover's weight room with Motsinger, New Hanover's head football coach.
Despite his "shortcomings," Walker, who possesses a 7-6 wingspan (90 inches), has garnered the interest of many college coaching staffs. Clemson, East Carolina, Maryland, N.C. State, Wake Forest, and UNC Wilmington have all extended scholarship offers.
Additionally, North Carolina has expressed strong interest, but has yet to join the fray.
"I hear they give offers late," said Walker. "So probably my senior year I might get one. I don't know. I'm not really worried about it too much right now, [I'm] just focusing on basketball.
"They just told me they are impressed with my performance, just keep working hard, and try to be the best I can."
Walker, who has attended games at UNC and Wake Forest, doesn't claim any favorites.
"I'm like wide open when it comes to colleges," said Walker. "I'm not going to leave any college out, because I never know what'll happen in the future."
However, Walker is a lifelong Tar Heel fan, as evidenced by the UNC shirt he wore to school the day of this interview.
"When I was younger I was always a fan of North Carolina, I always wanted to go there when I was younger," said Walker.
If UNC eventually comes through with an offer, Walker will weigh his allegiance as a fan against the loyalty towards those that have offered first.
"It would be a hard decision, because I had offers [come in] before and everything, and people have believed in me since I was in the tenth grade," said Walker. "It will take some thinking."
Walker will wait the recruiting process out, not making a decision until his senior year.
"It will come down to academics and coaches," said Walker. "They have to have coaches that want to work with you and spend time with you on and off the court."
