Because it's a week to week thing and hammering Wisconsin with your 3rd string QB is a lot more impressive than beating Iowa State.BCS 2.0
If we go by how the committee has been ranking them then I have no idea why TCU should get penalized for winning 55-3 over a bad team. Maybe if it had been closer. But then were 3rd for some reason and then get bumped down two all of a sudden. Musical chairs with the ranking by the committee.

I understand why it happened; I guess part of me was curious to see how they'd fare. Ohio State's win yesterday was certainly impressive, but it's tough for TCU to win by 52 (against a scrub team, granted) and drop out.
