McKie, a 6-foot, 175-pound athlete from Mauldin (S.C.), pledged to UNC over strong interest from in-state schools Clemson and South Carolina.
"[I like] the whole thing," McKie said. "The coaches, the campus, the surroundings – I love everything about North Carolina."
Two weekends prior, McKie attended South Carolina's Junior Day.
"I didn't feel the same when I went to South Carolina's Junior Day," McKie said. "I felt at home and welcomed at North Carolina."
McKie says his pledge to UNC is firm.
"No, I'm not going to [look into other schools]," McKie said. "I would say maybe – actually a slight maybe – if Texas offered, because I love Texas. But I doubt that will happen, so I'm about 100-percent sure I'm going to stick to North Carolina."
Without having a reliable quarterback to throw to him, McKie played quarterback himself in Mauldin's spread option offense as a junior. He'll remain at quarterback for his senior season.
Charlie Williams is recruiting McKie for UNC as a wide receiver.
"I would love [to play receiver]," McKie said. "My brother [Ryan] plays receiver at Furman and my dad [James] played receiver for the Gamecocks. And the position really comes natural to me."
McKie attended two of UNC's summer camps where he worked out at both quarterback and wide receiver. He was extended a scholarship offer following the second camp.
McKie plans to make a return to UNC's camp this summer, and will also be on hand for UNC's spring game.
