Standing 6-foot-10 and checking in at 280-pounds, Walker is a massive center prospect that began building his reputation during the summer.
A number of college programs have taken notice. Since AAU ball ended Walker has scored scholarship offers from Pittsburgh, Marquette, Seton Hall and Texas A&M, according to Wolfeboro (N.H.) Brewster coach Jason Smith.
"Pittsburgh is definitely the leader at this point," Smith told Scout.com. "That's the only visit he has scheduled at this point. I think he fits the style of play and and it's only about fours hours from his house."
"He's scheduled to visit them the 23rd of October," he added. "He's had some other people come through that are taking the wait and see approach as for as how he does with the conditioning."
Connecticut, Georgetown and Kansas are among the schools that have been in to watch him work out at Brewster. But none of the three have offered and are hoping he waits until the spring to make a decision.
"They've been in contact with him to see if he was going to sign early or late," Smith said. "They're probably going to wait and see if he goes late so they can evaluate him over the season."
"Initially he thought he was going to sign in the spring, but the longer the kids are here and the more they have people talking to them they get tired of the process and end up signing early," he added.
On the court, Smith has been impressed with Walker's abilities, but conditioning is still an area of concern.
"He's been pretty good. He's got unbelievable hands and a great footwork. He passes the ball very well for a big man. The thing that he needs to work on is conditioning. If he does that then the sky is the limit for him."
