I'm far from a fear mongerer, the exact opposite actually, but with how ultra contagious this thing is (despite that based on early data, the potency is quite weak compared to the other variants), it might be best for the league to take a break through the holidays and recalibrate in the 2nd week of January, use that as the "Olympic Break" since it seems like the Olympics are as good as toast IMO.
As annoying as it is to shut things down since the vaccines were supposed to put a stop to this sort of solution, it's probably best for business to pause for a few weeks since this should start to taper a bit after the holidays. Get everybody back to health and piece together a stricter protocol policy when they return.
