Well, you're kind of making our point as well and I don't think you realize it.
TCU won a playoff game...that's it. They brought home no hardware. Now, if their coaches hadn't gotten stupid, they could've won the Big 12 championship game. Don't you think they wish they had won that game? Big 12 Championship trophy in the case, Big 12 champs billboards all over DFW, put it on the stadium, etc.? Do you think they really wish there hadn't been a Big 12 championship game?? That game didn't prevent them from winning their semi-final playoff game, and it sure as heck had no bearing on them getting their asses whooped by Georgia.
You could make the case that the Big 12 championship game screwed them because they went undefeated...and in the past (SWC), doing that would win you the conference. But when you get to 12 teams, you have to have a championship game, and there will always need to be one going forward.
