Assuming you actually care about a rational response, here you go.
If we actually had rapid and accurate testing ... you could test players with confidence before and after games. Unfortunately we can't even accurately test governors who are in the presence of the president. The kind of thing that competent governments do is respond to pandemics with things like a comprehensive testing plan. With tests you have information, and with information you can act.
The experts you denigrate were indeed giving mixed messages back in March, and yes, they made mistakes. But later in the spring, as evidence became clear, there remained ambivalence on masks from some local, state, and federal leaders. It's pretty simple, if the nation had masked up we could help bring R0 below 1.0 across the country. However it's become part of the culture wars, and so instead of controlling the spread of COVID-19 this summer we've seen dramatic increases, particularly in the south.
Here's a good overview of how anti-intellectualism, among other things, allowed COVID-19 to bring America to its knees.
We probably should have had harsher lockdown for a longer period of time. This, followed by widespread mask usage, likely would have brought the pandemic under control and brought us back to some sense of normalcy by now. Instead we're talking about canceling fall sports and in the middle of some very, very difficult decisions about the extent to which we should open up public schools this fall.
