I'm not buying into Tennessee being a much improved team. 
Kentucky has covered its last five home games. The Wildcats have gotten their weak QB play straighten out with the decision to make junior wide receiver Lynn Bowden Jr. their QB. Bowden has been very effective running the ball. He's a tremendous athlete who gives the Wildcats a different dimension from their previous QB's, Terry Wilson and Sawyer Smith.
Alabama and LSU draw the SEC headlines. Quietly, though, Kentucky has covered eight of its last 10.
This is just the Volunteers' third road game. They lost their first two by 33 points to Florida and by 22 points to Alabama.
