A quick a dirty run down starting with the easiest and working down from there.
Big 10- They are done with expansion unless ND comes a calling.Pac 12- They are done with expansion unless Texas comes a calling.
ACC- Waiting to find out when Pitt and Cuse will play but otherwise seem to be done with expansion unless ND comes a calling.
SEC- Pretty sure Mizzou is as close to a done deal as there is with the leaked website and rumors but who knows when this will be announced. Appear to be done after they get 14.
Big 12- Waiting to see what Mizzou is going to do but they added WVU after a little intrigue with Louisville and politicians since it’s not Big 12 business unless some politicos get involved. The rumor was OU, Okie St and TT where pro Louisville and a 10 year assignment of TV rights while Texas was pro WVU and 6 years and from the looks of it Texas won again. Conflicting reports on what they plan on doing and most likely they don’t know yet. They can stay at 10 or 11 (if Mizzou stays for some reason) or they can add 2 more. The 3 teams mentioned most often are Louisville, Cinci and BYU. Apparently BYU is requesting same day replays for the BYU channel and 3 live games which the Big 12 is not going to agree too.
Big East- The rumor is by Friday UCF, SMU and Houston will be asked to join and accept as full members and Boise St will accept being a football only member. Air Force and Navy also apparently will accept football only membership but no time table. Army declined to join. They are also looking at either BYU or Temple for a 12th team.
I have not seen how this will affect the CUSA/MWC superduper conference but really who cares.
