So it looks like, for now, the Big-12 is going to go ahead with fall football. Updated schedule coming soon. Big-12 is also committing to heart imaging diagnostics for athletes that have had COVID. The SI reporter, I mentioned earlier, however, has said a Big-12 source said, "This doesn't mean we're going to play. Students are coming back to campus..." Implication that if the COVID situation deteriorates, then canceling is still an option.
So the Big-12 is still hedging.
Honestly, I'm not sure how this helps athletes. Sure, if everything works out, that's one thing. But if you feel like there are still decent odds you might have to cancel, then it seems like it would be even more devastating for the players to train hard for another month and still have the rug ripped out from under you. At least, if it's cancelled, you can make decisions, adjust your mindset. Like when you know you have to do something you really don't want to do, so you procrastinate as an avoidance tactic, and all you do is fill yourself with dread. And after you do the thing, even though it sucks, the moment passes and then you feel freed from this thing that had been hanging over you.
