Indeed, more offers have come in. Later that day, Utah extended Rankin, a 5-foot-11, 179-pound safety from Salisbury (N.C.), his second scholarship offer.
"Wednesday was a pretty good day," Rankin said with a laugh.
The UNC offer has more meaning, outside of being Rankin's first. His mother "loves" the school and he "likes [it] a lot."
"I think it's a real good school," Rankin said. "They take good care of their student athletes. They show that they really care. They already treat me like I'm on the team. Academic-wise, it's very good."
Regardless, Rankin denies having any favorite schools.
"It's pretty wide open," Rankin said.
Before the end of the summer, Rankin plans on establishing a favorite schools list. He figures to make a verbal commitment sometime between the middle and the end of the football season.
Along with teammate Romar Morris, Rankin participated in the Wednesday morning session of UNC's three-day camp. He spent a good portion of the session working out individually with Everett Withers, UNC's defensive coordinator.
"He had me working on opening my hips and keeping my feet under me when I break up on the ball and keeping my head on a swivel – back to the quarterback then to the receiver," Rankin said.
During one-on-one drills, Withers pulled Rankin aside and verbally offered him.
"He told me I was very athletic and I didn't give up on plays – if I slipped and fell, I didn't give up," Rankin said.
After the camp session, Rankin and Morris went to Butch Davis' office where he was given the official scholarship letter.
"He didn't want us to commit just because we were there," Rankin said. "He wanted us to commit because that was the best place for us. He wanted to make sure we knew there was no pressure."
Before leaving campus, Rankin and company spent some time with UNC's assistant coaches and a few players, including some of the incoming freshmen.
Rankin has also camped at South Carolina and will camp at Utah on Tuesday. He also plans on camping at Clemson and Wake Forest.
