There are probably only going to be 4 SEC teams in the playoff.
1 gets a first round bye, we host one, and the other two have high probability of being in other parts of the bracket, so if we are "lucky" enough to land in same bracket that has the SEC bye, we'd likely play only 2 SEC teams.
My thing is just to maximize our home field advantage. Hosting any of the other cold weather teams doesn't do that...either Miami or one of the SEC teams does (not Tennessee as much).
