I gotta think they'll need to reload out west first. However, I would think La Tech would want to block any Louisiana schools (and UAB any Alabama schools out east). Dunno if La Tech has that much pull but I think C-USA knew the Louisiana situation when they took La Tech. I would think Rice would get into the BE if Houston leaves. I think C-USA will need Texas State and Arkansas State to help rebuild the west especially for recruiting purposes.
So you have Tx St, N. Texas, UTSA, Ark St, La Tech, USM as a west division
My east would be UAB, FIU, FAU, MTSU, WKU, Marshall (I have Charlotte and ODU to the BE but swap schools in this division depending on who you think would leave).
Regardless I think it's safe to assume Tulsa and UTEP will be gone, the only question is where they end up. UTSA is a bit of a flight risk depending on the MWC/BYU/UH/SMU situation. If Houston and SMU stay in the BE and bring in Tulsa then keep Rice in C-USA and add Ga St out east.
Not sure Texas State makes it in...if they are going for markets UTSA/Texas St have lots of overlap.
Also LA Tech hates ULM (their neighbor in North LA on I-20, and feels that they're not worthy to be in a conference w/ them) not so much ULL (they are all in the same system but ULL is the flagship and has some pull over LA Tech they could use). Still Tulane/LA Tech have the state pretty well covered so I think Arky St and WKU are the replacements for Tulsa and the other non-Texas TBA school (assuming UH/SMU stay) with GA State on deck.
West - UTEP, UTSA, Rice, UNT, Arky St, La Tech, USM
UAB (could go East or West depending who they lose, but let's say its UNCC/ODU)
East - UAB, FIU, FAU, MTSU, WKU, Marshall, Charlotte/ODU
Now if UTEP (MWC) and Rice (nBE) leave I think Georgia St is next in line and am split between Texas St/NMSU for 14.
West - NMSU/Texas St, UTSA, UNT, Arky St, La Tech, USM, UAB
East - FIU, FAU, GSU, MTSU, WKU, Marshall, Charlotte/ODU
If more defections happen ULL/Troy are on deck followed by more upgrades Liberty/UDel/AppSt
