"I'm looking for a school with good people that I can relate with,'' said the 6-foot-10, 275-pound Walker, who grew up in Toronto. "I want a good team, a good program, a good school with good academics, a place that's close to home, and stuff like that.''
So, even when Hill or a Rutgers assistant is not present, Walker is getting his fill about the Scarlet Knights from Carroll and his family.
"They told me everything about the school, and I take everything they say back to my circle of people and get their feedback,'' Walker said. "Right now I like what they have to say. I like what I see from Rutgers.''
Still, Walker is listing Pittsburgh as his favorite, but acknowledged it is because it is the school he knows best.
Walker already took an official visit, and also tripped to Pittsburgh unofficially. He will use that experience to compare his remaining schools before making a decision during the spring signing period.
"It's the school I've seen, and I like what I saw when I went,'' Walker said. "I don't really have a point of reference yet, other than Pittsburgh. I like the people and I felt a connection. I met the players and the coaches.
"My mom and dad were both there, and they met the academic advisors, and that's their main concern, academics. My parents like it, and I like it, and it's what I'm familiar with right now.''
Walker hasn't scheduled his other trips, but said he would be visiting Rutgers. He is averaging 12.5 points per game, and could play significant minutes if he chose the Scarlet Knights, who is are dire need to sign at least one big man for next season after Greg Echenique's stunning mid-season transfer.
However, early playing time will not be the determining factor for Walker.
"I'm more worried about, in the early stages of my career, just developing into the player I want to become,'' Walker said. "Just changing my body and things like that. I'm more focused on that in my first couple of years than anything else.
"If I can do that, and get playing time, that would be perfect.''
