The WAC as a going concern will be dead by July 1. It will linger for a couple years while future moves are executed.
But, you're going to see the Texas schools all go back to the Southland (Abilene Christian, Tarleton, SFA, UTA), at least temporarily. And the 3 Utah schools all go to the Summit.
That would leave just Cal Baptist without a home. Although UT Arlington as a non-football is likely to continue to pursue other options, including the Valley.
It is also possible you see a new southern/southeastern basketball-only league start with something like this:
Bellarmine
Florida Gulf Coast
Jacksonville
Lipscomb
New Orleans
Northern Kentucky
North Florida
Texas Arlington
Texas A&M - Corpus Christi
