K.T. Harrell launches a jump shot for the Cavaliers in a game vs. Virginia Tech.
He signed with the Cavaliers out of Brewbaker Tech in Montgomery where he was rated as a four-star prospect by Scout.com. He was ranked as the No. 8 shooting guard prospect nationally.
Harrell noted that he didn't leave Virginia at Christmas time without seriously thinking out the move. "It was a tough decision to leave," he said.
"One of the reasons I did it was to be closer to home and my family," he pointed out. "Also, the style of play wasn't what I was expecting. I had always played an up-tempo style and that is what I thought we would be doing at Virginia."
