The B1G is out, the PAC is probably next. I think the Southern States will still give it a go or at least wait until the very last second to decide to call it off.
My guess is the MWC follows whatever the PAC does. If the PAC calls it off the 3 Cal State schools will be forced to follow the UC schools decision. The New Mexico Governor already said UNM shouldn’t play. Hawaii is a question mark. Colorado State is a mess right now. Hard to see many Mountain West Schools pushing for a season at that point.
