I don't put all that much faith in statistics, as I'm sure you don't either. However, the defenses Tennessee has played against (on average) are considerably better than the offenses South Carolina has faced.
The worst offense Tennessee has faced was Florida (#59). South Carolina has faced some pitiful defenses...Furman (worse than the last one listed at #124), Vanderbilt #122, and Missouri #68.
I believe Tennessee will score a lot of points. If the embarrassingly inept Vanderbilt can hang 34 points against you guys, the Vols offense will roll.
As a Vol fan, I am much more worried about the other side of the ball. While we do have a good defense, I think South Carolina's offense will put plenty of points on the board.
