"Obviously the quarterback situation will be open after this year," Thompson told Inside Carolina on Sunday. "That's the first thing that drew me here.
"And, I live right next to UT; it's always been where I wanted to go, but they got Crompton, so they really have never recruited me very hard.
"I was on the edge between Clemson and North Carolina, but when I talked it over with my parents, I decided North Carolina was the place I wanted to go."
Thompson, who has thrown for over 3,000 yards and 29 touchdowns over the last two seasons, describes himself as a straight drop back passer who will runs only when necessary.
"I'm not much of a runner at all; I'm pretty much of a shotgun and a straight drop back passer," he said. "I'll throw out of the pocket every now and then."
Thompson's Rebels began practice last week. He said his team is poised to win their second state 4A championship in three years.
"We definitely want to win the state," Thompson said. "This is one of the best teams that I've ever been on."
He also said he is glad the decision is behind him so he can concentrate on his immediate goals. Then he can look forward to his college career at UNC.
"If John Bunting can have a good year this year, I think we can get back on track."
