The Tar Heels are recruiting Thornton the hardest, but the first school to offer a scholarship was the Pirates.
"Only one talked about offering is ECU," said Thornton. "A lot are looking for me to come to camps. I'll go to Carolina; I'll come to Duke, Tennessee, Virginia, Georgia Tech, and maybe Auburn."
The lack of offers hasn't deterred Thornton in establishing favorites.
"My top three is Carolina, Tennessee and Georgia Tech," said Thornton. "I like each of them. Carolina, I've been down there several times. I just like the overall program and the feel they have. They take care of their players after they leave and I like that.
"Tennessee, I haven't been there yet, but there's something about it that brings me into that. It's the same way with Georgia Tech."
Thornton has been to both North Carolina and East Carolina "a lot," and liked what he saw at both campuses. He is in the midst of planning a trip to Clemson.
At 6-foot-2 and 221 pounds, Thornton clocked a 4.97-second 40-yard dash, 4.66-second 20-yard shuttle, and 7.78-second L-cone drill. He also recorded 29 inches in the vertical jump and 8'10" in the broad jump.
