Not sure about anyone else, but I am down with Western Athletic Conference football in 2022.
Sam Houston State
Stephen F Austin
If you are Sam Houston State and Stephen F Austin, you maintain the Battle of the Piney Woods.
Lamar will and could still play McNeese out of league play and SFA can do the same with Northwestern State. I doubt those schools would want to give up those rivalry games especially with the short travel.
The new, constituted WAC would likely need to add one more school if not two. Ideally UTRGV would add football and I know there's talks of Southern Utah (which would be an hour commute from Dixie State, great for non-football sports!) to help fill a few more slots on the schedule but you could easily have plenty of SLC vs WAC games, plus WAC vs SWAC games for the OOC play.
