Anyone looking at schedules should have expected Auburn to be 4-0 coming into Knoxville. I think it will be a tight game (but hopefully better than last year), and UT will come out ahead... although I am not expecting a blow out either way. For UT a loss could be a big setback for the season and realistically make it difficult to get to 6-7 wins. A win, on the other hand, builds momentum going into the Georgia game.
A loss for Auburn, likewise, could start a downward spiral. They would still have games at Arkansas, LSU, and Georgia, and some tough home games against Ole Miss and Alabama. Kentucky may also present a challenge at home, so the only easy game left on their schedule is against Furman. So even though they will likely have 4 wins coming into Knoxville, they are likely looking at a 6-7 win season as well.
