impossible. To get in, BYU needs USC to win the Pac-12 and to win every other game except against the Cougs. We'd need Baylor to keep winning and beat Oklahoma, Boise to win the MWC, Cinci to lose at some point and probably Oklahoma to have a second loss at some point. And we'd need the entire ACC to do what the Pac-12 is doing.

SEC will get at least one
Big Ten will get one

BYU would have to jump the ACC, Pac-12 and ACC, because the SEC would get a 2nd team in before we get in.

That is how unlikely it is. I think it is pretty accurate to say chances are nil.
