Houston lost its shot at the BCS with style. Southern Miss won the C-USA title 49-28.
That knocks Houston out of the BCS. It was such a bad loss, it might even knock the Cougars out of the at-large pool (not that it matters -- they wouldn't get picked). A blowout like this could cause a precipitous fall. They might even fall far enough to help out Michigan.
Now, the clock is on TCU. If the Frogs win today and can move up two spots to 16th in the BCS rankings, they would automatically qualify for the BCS as the highest-rated non-AQ conference champion. TCU is up 21-3 in the first half as I type this.
If TCU is unable to move up two spots, it opens the door for a Big 12 team (Bedlam loser, especially if Oklahoma State, or Kansas State) or even Boise State.
The day is still young. This could change again.
