The only sports that somewhat safely could should be played at this stage played are:
Pro Tennis: With little to no crowds
Pro Golf: Same
Everything else should be shut down, and possibly try to open by April 2021 (Major League baseball season) at the EARLIEST. Ideally, there will be no college sports until Aug./Sept. of 2021. Give us time to get solid vaccines and time for them to take effect.
Of course sports talk radio, TV folks, owners etc. are having baby cows about the shutdowns, but you know what? Desperate times call for desperate measures.
