UNC's scholarship crunch may ultimately factor into the decision by the 6-foot-3, 211-pound tight end from Hackensack (N.J.).
"That's going to be an issue," Bush said of UNC's scholarship situation. "But we'll know by the end of this week how that's going to go.
"They are over-signed right now, but they have a couple of players who might not qualify."
Bush, who was accompanied on his UNC official visit by his father and brother, unofficially visited UNC during the season when the Tar Heels defeated Notre Dame, 29-24.
"This time, I was able to see how the players interacted with each other and how they spend their time," Bush said. "I got to see more of the campus and the academic side of the school."
Throughout Bush's stay, he was hosted by Ed Barham, a fellow tight end.
"Ed is cool [and] a good guy," Bush said. "We had a lot of fun. He took me around and showed me a lot. I'll probably keep in contact with him."
After spending much of Friday night with Barham and other players, Bush met separately with both Steve Hagen, UNC's tight ends coach, and John Shoop, UNC's offensive coordinator Saturday afternoon.
"They both talked about my role if I were to come in and play tight end and how I would gradually move into that role," Bush said. "They talked about the stuff I'll be able to do as a freshman. They're looking at me as an H-back. They said they're going to get me the ball – basically, give me a chance to make plays."
Saturday night, Bush attended UNC's basketball game against Miami.
"It was a good experience," Bush said. "The University of North Carolina basketball is very prestigious. So it was a cool experience to be there and be around the players."
Bush closed out his official visit with the customary meeting with Butch Davis.
"Basically, [he discussed] the opportunity I'll have to play and that they really want me to come," Bush said.
Bush doesn't have a timetable for the remainder of his recruitment, including when he'll make his collegiate decision.
"I'm going to sit down, think about it, rest on it a little bit," Bush said. "I'm still open if anyone else comes in, but other than that I'm just going to think about Pitt and North Carolina."
