The P5s are consolidating. This does not bode well for BYU.
BYU could end up in a diminished B12 that has a status somewhere between P5 elite and G5. But BYU will not be in the mix with the elite and big money conference. The money will reside with the SEC, B10, ACC, and P12 (if they play their cards right). The B12 might continue to exist but will have little brother status to the others.
