I think heading into this without knowing the rankings I would have assumed the Big 12 would have a spot ahead of us, leaving the playoff as SEC, B1G, Big 12 and ACC. However, seeing where Baylor/OSU/Oklahoma/TCU were ranked the first couple of times through gives me some hope. I think if Baylor and ND win out, and Stanford wins the PAC12, there's going to be quite a ruckus around which of those teams belongs in with the 4th spot.
However, it's college football, so I'm assuming someone is going to lose that changes the whole picture. I think ND gets in if they win out the rest of the way, more because someone else tripped up than they earned it over an undefeated Baylor/OSU
