The visit would be key for UNC, which finds itself playing catch up for Marshall, a 5-foot-10, 170-pound cornerback from Durham (N.C.) Southern.
"Wake Forest is my leader," Marshall said. "And then its Duke and Virginia Tech and then Carolina, right now.
Wake Forest's "family environment" has it in the driver's seat.
"Coach [Jim] Grobe, he has done a lot of different things with that program," Marshall said. "So many people support the program in the city of Winston-Salem. And the coaching staff, they make me feel so welcome whenever I go up there... With the system that they run, I feel like I would fit right in."
Marshall is aiming to make a decision before his senior football season kicks off.
"My parents and I are considering it," Marshall said. "I want to get the whole process out of the way before my senior year to avoid distractions. I can't say that's exactly the plan, because there's a possibility it won't happen but most likely it will."
Before pulling the trigger, Marshall wants to have his parents on the same page.
"Right now, I'm just trying to get my parents around and more into the recruiting process [before deciding]," Marshall said.
Marshall admits that there is a chance he could commit to a school while visiting with his parents.
"If we go somewhere and both my parents feel it's the right place and I feel like it's the right place, there's no telling," Marshall said.
Marshall's father has visited Duke and Virginia Tech.
Marshall has made countless visits to UNC. Roughly a month ago, he made his most recent visit with his coach, Adrian Jones. He spent a few hours on campus speaking with coaches Ken Browning and Everett Withers and got a lot of his questions answered.
"It went very well," Marshall said. "Pretty much, they answered all my questions about classes, schedules, all the rebuilding they're doing – stuff like that.
"They're rebuilding a lot in their coaches' office and meeting rooms and they showed me all that. They also showed me their recruiting board and showed me I was No. 1 on their list – they weren't pulling my leg. They let me know that I was a priority over there."
Marshall was flattered to see his ranking on the recruiting board, but says it won't improve the Tar Heels' chances.
"I can't really use that as a stepping stone to how much I like them," Marshall said. "It doesn't really mean anything to me. It's an honor, it's a blessing, but that's not going to make them my favorite."
