If CUSA raids 3 teams from the WAC, which looks like it everyday.
Sunbelt and WAC may be forced to merge since 1 will be short of 8
After the 16-team fiasco, they are not going to go to 14+, and I think they will even stay clear of 12 until the see what the MWC does.
I expect they will grab the 3 "in the area" teams of ID, NM ST and UT ST because:
1. It gives them a buffer in case the MWC (or CUSA again) comes calling for a team or two.
2. Given none of the SB teams are going to help the TV deal, etc. their main issue will be keeping travel costs as low as possible.
I can see them grabbing North TX in place of one of those teams since It's the best of the SB and "sort of close" to UTEP and LA Tech
Of course, this will leave 6 SB teams without a conference. They, along with FL A&M would have to form some "unofficial conference" that would provide everyone 3 home games each, but #4 & #5 may be tough to set up.
I guess then you would see them trying to convince some 1-AA team to move up so they could get 8 members.
Luckily, even as a faux conference, they may still be able to keep the New Orleans Bowl, since nothing prevents the bowl from making at deal with 7 individual schools instead of a true conference entity.
