O.k., come on - really what the colleges are seeing is that some MLB teams are shut down because of cases. They can see that this would happen to many college sports teams. Right now they are not travelling - what is going to happen when they put a whole football team on a plane, to get to a ridiculously far-off conference opponent? Or, two or three planes, to allow for distancing? And then buses to and from the airports? They can see what will happen, and why pay all that money for travel, hotels, etc., only to be shut down after a couple of games anyway?
They should have scrapped conference play, and only played local. Use school buses with open windows. Coaches and staff drive themselves. No, it's not the accustomed luxury, but it's playing. There are creative ways to do everything, but most institutions aren't taking them, they have this idea it has to be all or nothing.
They never worried about concussions, so I don't see why they would worry about myocarditis.
