Reynolds, a 6-foot-2, 190-pound safety, had already been listing UNC high among his top schools heading into the visit.
"I don't have a [clear cut] leader, but my top two right now are definitely Stanford and UNC," Reynolds said.
"I just think, Stanford, they've been playing really well this season. They definitely have them going in the right direction. Academically, they're second to none. And it's just a place, when I went up there, really attracted me.
"With UNC, it's the same thing. Coach [Butch] Davis is known for being a great coach, sending guys to the league. The environment there is great. It's a great school. I have family around that area, so it would be convenient for some of my family members to come see me play."
Saturday's visit marked Reynolds' and Olaniyan's first trip to Chapel Hill since camping at UNC in June. It was also their first game at Kenan Stadium.
"I thought the atmosphere was great," Reynolds said. "I knew it was [against] Georgia Southern, so I knew it wasn't going to be packed like it would be for any other game like an ACC game. But even for Georgia Southern it was a pretty good crowd.
"I liked the fans and the support the football team gets. I liked the environment overall. It's definitely a place I can see myself playing."
During lunch before kickoff, Reynolds and Olaniyan conversed with UNC assistant coaches Troy Douglas, Charlie Williams, and Everett Withers.
"We got a chance to sit down and talk to them, get their ideas about stuff, talk about setting up an official," Reynolds said. "Building that relationship with them is key [and] we definitely got a chance to build on that relationship even more."
Reynolds and the UNC coaches didn't settle on a special weekend for the official visit. However, with Reynolds' school and football schedule, all of his official trips will occur after the football season. He and Olaniyan will likely officially visit UNC together.
Reynolds said he has been thinking about his official visits a lot lately.
"I think as of right now [I will officially visit] North Carolina, Stanford, probably NC State – those are the three I know for sure," Reynolds said. "Most likely Duke [will receive an official visit] and the last one might go to Vanderbilt."
Northwestern and UCLA are competing with Vanderbilt for Reynolds' fifth official visit slot.
Regardless, Reynolds says he's "concentrating the most on" Duke, UNC, NC State, Stanford, and Vanderbilt.
Reynolds isn't exactly sure when he'll make a verbal commitment. "I want to let the season play out so I can focus on my season, as well as see how teams I'm interested in do in their seasons," Reynolds said. "I want to take my officials before I make the decision to commit. It will most likely be after a couple of officials, but that's open to change."
