Tennessee's relentless pursuit of Dixon paid off.
"It's feels good to be committed," said the 5-foot-10 1/2, 178-pound Dixon. "What separated them is they showed me a lot of love and Tennessee has been there since my freshman year.
"I'm very excited and and it's great to have my decision made before the season. Now, I can just focus on high school and trying to win a state championship."
Running backs coach Robert Gillespie played a pivotal role in his decision.
"We communicate all the time," Dixon said. "Even though he's not my recruiter, he still always stayed in touch and built a strong relationship with me. We talk about everything.
"He's told me I can come in and make a big impact. He said I remind him a lot of (former Tennessee running back) Alvin Kamara and they feel like I can do the same things he did at Tennessee."
Dixon is looking forward to playing for head coach Butch Jones.
"He's done a lot for the program and the city of Knoxville," Dixon said. "He's turned the program around and done a really good job recruiting.
"He's also a really nice guy and really cares about his players. I think they're going to have a great season."
Dixon said he is 100 percent committed to the Volunteers.
