The 6-foot, 185 pound senior has tripped to Tennessee more than any other the school over the past year and the Vols sit on top of his list.
"Tennessee is my favorite," said Corker. "It is the place I feel the most comfortable at right now."
The Vols have done a great job making him feel wanted, needed and like a priority. When on campus, Corker gets attention from multiple Tennessee coaches and, at this time, all are chasing the program Butch Jones runs.
Tennessee may or may not receive an official visit from Corker. He is very familiar with the program, it is a school fairly close to home, so he has trips to schools farther away so far.
"I know I will also take an official visit to Michigan State, but I do not know the date yet.
"I am really down to those four schools, Tennessee and Virginia."
Corker took a visit to Virginia recently to see the Cavaliers play North Carolina.
The quiet defensive back has picked off two passes this season, he will hit the road for official visit No. 1 next week, and he plans to make his decision in December.
"I am committing on my birthday — December 26," said Corker.
