I have looked more at the two rosters than I normally would for a game like this... and I don't think I'm going to be surprised. For instance, UT's OL will avg an inch or two in height more and about 15 lbs more without sacrificing athleticism.
I believe if you make the game you'll have a nice time seeing the Smoky Mtns. I think you'll have the experience of a lifetime visiting Neyland. I also think you have set yourself up to be very disappointed with the competitiveness of the game.
The more I look at the two rosters, the more I am led to believe it will be a game much like WKU (another good mid-major expected to come into Neyland and spring an upset).
