Six teams left - Hawaii, San Jose State, Idaho, Louisiana Tech, New Mexico State, and Utah State.
Hawaii is also talking independence, which would be fine if the Warriors (not the Rainbow Warriors, anymore, right??) just want to play in their home bowl, and host a big name or two each year.
Utah State is still looking at joining the MWC. They were invited, along with Fresno State and Nevada, so that might still happen. If so, the MWC would be up to 11 teams, and might take another from the WAC if Houston or SMU can't be lured away from Conference USA.
Louisiana Tech is out of place in the WAC, and always has been. They'll go to Conference USA the next time the conference memberships shift around.
San Jose State, New Mexico State, and Idaho might just try and pick up the pieces and settle for being a lower-tier Division 1 conference, inviting some of the better 1-AA programs to jump up (Montana from the Big Sky is a likely option. Nevada, Boise State, and Idaho are all former members of the Big Sky Conference).
