KC Run GMC coach L.J. Goolsby confirmed the news to Scout.com.
"He told me he basically loved the college campus atmosphere when he went on his visit," Goolsby said. "I think one of the other factors was Dom Collier going there. They have a pretty good relationship. I think that helped."
"Dom was with him there when he was there for his official visit," he added. "That really helped put his mind at ease since he knows someone else going there as well."
"Coach Boyle had recruited him personally pretty hard," Goolsby said. "Tory felt really comfortable with them and the rest of the staff. I think he feels he has an opportunity to go play freshman if he takes care of his business. He's pretty excited about it.
