Texas has absolutely no chance to get in. Vandy either, almost certainly.
The Longhorns are 9-3 with a bad loss and a blowout loss (not to mention multiple great escapes in OT against bad teams), and the committee set the precedent last year that power conference championship games losers get a free pass on that championship game loss (at least if they aren't blown out, as last year's games were all competitive).
And it's not even as if computers like them—they're 16th right now in what has become my go-to composite rating of nearly 100 different rating systems compiled by
Massey Ratings. They're also 14th in the AP Poll, which has been in close alignment with the CFP Rankings.
