I know that we're talking significantly fewer players and staff (and a shorter time frame), but I'll be really interested to see how things play out with the bubble process the NBA developed. I believe that teams have been in their bubble now for 3 weeks and I don't think that anyone has tested positive yet. Pretty strict protocols too for those who have to leave and then try to come back in.
If there was a league that had the financial wherewithal to do something similar (albeit on a much larger scale)...it would be the NFL.
But like most here, I fear that, absent a bubble, players and staff exposed to the general population (and/or their families exposed to the general population) will undoubtedly become infected.
