In addition to UNC, Rayner, a 6-foot-3, 220-pounder from Leland (N.C.) North Brunswick, has collected scholarship offers from Clemson, Duke, East Carolina, and NC State.
"North Carolina is one of the top programs in the ACC," Rayner said. "It made a bowl game [last year] and they've produced some good linebackers.
"I'm pretty interested [in UNC]. I want to get down there by the end of the month and check it out."
Regardless, Duke is Rayner's favorite school right now.
"Duke is a pretty good school and football is making a rise," Rayner said. "I'll probably be open more after I take more visits and actually see other schools."
Rayner has only made visits to Duke, East Carolina, and NC State thus far.
Besides a possible late May trip to UNC, Rayner is considering visits to Auburn, Clemson, Florida, NC State, South Carolina, and Virginia Tech.
Rayner doesn't anticipate making a verbal commitment until after taking all five of his official visits, which will likely take place following his senior football season.
Rayner's conversation with Pittman was the first time he's personally spoken to a UNC coach. He has, however, received plenty of mail from the school and invitations to junior days through his high school coach.
"They wanted to check their P's and Q's – that's what [Pittman] told me – before they offered me," Rayner said.
Pittman made an evaluation visit to North Brunswick earlier in the week, while Art Kaufman visited a week prior.
Midway through his freshman season, Rayner broke into North Brunswick's starting lineup at defensive end. He held down that role until early into his junior season when he was moved to linebacker. He ended his junior season with 127 tackles, including seven for a loss and two sacks, and two forced fumbles.
At the Shrine Bowl Combine held in Williamson, N.C., Rayner registered a 4.66-second 40-yard dash, 4.53-second 20-yard shuttle, 8-foot-2 broad jump, and 28 reps of 185 pounds.
