A 6-foot-6, 290-pound junior offensive tackle from Alexandria (Va.) Williams, Whitmire has also received official scholarship letters from Pittsburgh, Penn State, and Virginia.
Whitmire says it's too early in the process for him to name favorite schools. Additionally, he isn't sure when he'll make a verbal commitment.
Off the advice of his head football coach, Whitmire decided to adjust his schedule and attend UNC's two-day camp.
"My coach, Coach [Dennis] Randolph, he had told me that I should go down to the North Carolina camp," Whitmire said. "I had to take off some school, take some final [exams] early or make them up. He just told me that North Carolina wanted me to go to their camp."
Throughout the camp, Whitmire worked out under Sam Pittman, UNC's offensive line coach.
"Coach Pittman is a pretty cool dude," Whitmire said. "He really helped me out a lot with my pass blocking. He's a pretty good coach."
In July, Whitmire returned to UNC with his teammates. Williams High participated in the Tar Heels' seven-on-seven camp where Whitmire played out of position at tight end.
Both aforementioned camps marked Whitmore's first and only UNC visits.
"I thought it was a pretty cool experience," Whitmire said. "They had some nice practice fields and facilities. I liked it. It was a fun camp."
In addition to UNC, Whitmire camped at Penn State and Virginia, and joined his Williams teammates in Pittsburgh's seven-on-seven passing league.
This weekend, Whitmire will attend his final college game of the season – UNC versus East Carolina in Chapel Hill.
"We play Saturday games – our home games are on Saturday – so it's tough to go and see a college game," Whitmire said.
Whitmire has already attended Virginia's upset loss to William and Mary and Penn State's defeat of Syracuse.
Midway through his freshman season, Whitmire broke into Williams' starting lineup as a defensive end. He started both ways – offensive tackle and defensive end – his sophomore season.
