We are going to continue to see movement as schools jockey for position. I do not see either the PAC12 (with SWT.....haha Tx State) or the Mountain West ever really making noise and having success in the CFP, even if expanded to 16 teams. But, I have been wrong before, many times.
I saw where Texas run ruled LU last night. Surprised that I beat someone to posting this I am hearing that Texas is going to be really good, so I am not reading much into this for LU and their season, at least not at this point.
It's a little interesting that a more or less new twist is occurring in FBS as both of these moves are for football only. NDSU is a member of the Summit for all other sports. The Summit doesn't have enough football playing schools to have their own conference. Both the MVFC and Big Sky have football only members from other conferences with more than enough to maintain their automatic bids so neither should have to hunt for immediate replacements.
