Why can't the big xii be shut out again? It will happen unless the big xii champion has a better record than #4 or OU or TX are undefeated which does not appear plausible in 2015.
I do think TCU gets in this year an in fact I think they have all the tools to win it all. However they ( Or any B12 Champion) will only get in if the other 4 P5 conference champions have more losses. The lack of having a B12CG is huge to the committee as demonstrated last season.
If the Big XII gets left out again, then unless the Big XII clearly just doesn't have a team deserving, then Boren may pull the trigger and take OU someplace else if the conference refuses to make any moves.
