I guess I just don't see it this way. ND is a media darling. They love to talk about ND, they used to do just about anything to get them in the BCS, even with more losses than every other team available. They are always ranked unless they totally **** the bed. They have a lot easier road to the final 4 doing it like they do now, being able to basically pick and choose their schedule. They'll never be tied to 9 conference games and can go ahead and keep their schedule about half full of cupcake games.
The ND name definitely holds more wather than TCU or Baylor. No way a 1 loss ND gets left out of this years playoff. As has been said a lot already. The non-championship game was just a convenient excuse. It wouldn't surprise me to find out that that the committee called ND right after the game and emphasized to them, "Don't worry, this championship thing doesn't pertain to you."
The only way ND ever joins a conference, is if the committee comes out and says there is a rule, "To qualify, you must play in a conference championship game." Even at that point, I still wonder if ND looks at all their piles of money and wonder if a title is really worth sharing some of that cash.
Hell, don't fool yourselves. If Miss. St. wouldn't have lost their last game, they wouldn't have played in the championship game and yet, they would have been in the playoff. Until they lost, it was pretty much a sealed deal that they were in as well as Alabama.
