Evolutionary biologist Bret Weinstein did a podcast with Rogan. Weintsein studied bats his whole life (he did his thesis on them). He said he thinks that because bats are always in the dark, that bat coronaviruses are poorly adapated to UV light. Even the 1918 flu (not bats) was known to be ameliorated by sunlight and patients were moved outside.
I don't think being outdoors in sunlight, wind and wide open spaces is much of a threat for a respiratory coronavirus. It seems like the real threat comes from being cooped-up indoors with other people. In the east, its the winter months that create a problem, and in warmer states its the higher temps that drive people indoors for the AC.
If someone put poison in a glass of water and I drank it I could get ill. If someone put the poison in the reservoir nothing would happen. That's how I feel about indoor vs outdoor virus risks.
With sports, people are breathing heavy and in close contact, so there would be more of a risk but maybe not much more. I think something like OL/DL play could be riskier because guys breathing hard have their faces in each others grills for the whole game. Playing soccer outside, I don't think I would worry too much. Protecting or rushing a QB in November would make me more apprehensive but not a lot. I could be wrong about that though - spesh because who knows how virus has changed by then. Vitamin D is also very protective and being outside helps
