The very purpose of social distancing is to to avoid the droplets than hang in the air for a short period after an infected person breathes, talks, coughs etc. It is to avoid taking on viral load. There is an entirely different scale of risk between playing football in the open air and in a closed environmental setting when there really is no escape from the virus.
Contact tracing studies show that 0.03% of infections took place in an outside setting so I suggest if fans feel that football is depraved then they focus on other occupations, and employers.
Do you think maybe a few droplets might pass between people in a full contact sport.
The fact that they're advising people to turn their heads away when tackled should tell you everything you need to know about how safe it is.
