Things are going to look very different in a few months. Just because the dorms shut down and classes went online, the players didn't stop meeting with friends, going to house parties, hooking up with girls. They're not social distancing and they're not wearing masks. They're young and they feel invincible and they're not taking a lot of precautions. By the end of the summer, I believe it's highly likely that many of them will show they already have antibodies for this.
The "if one player tests positive" rhetoric will be meaningless, because hundreds and perhaps thousands will have already had it and be testing positive. Non-athlete students in classrooms will have had it, or will be getting it and testing positive, too.
People keep making the mistake of looking at it through the lens of our current enivronment. Things will look a lot different in a few months, which is precisely why nobody should be making far-reaching decisions about the future, right now, because they simply don't have to.
