It is not the "strong fit guys" that we are worried about that closed the leagues for, it is the people around them. Normally think about the games with absolutely no lockdown, there are tens of thousands of people watching right? Well, remove all of those people and you are not left with just 22 people.
We are talking about stadium personal, the staff, the waiters, the coaching team, the doctors, the security and god knows who else I am forgetting about, so it is not really all that easy and each game has at least 50 people, probably more, plus you are risking that 50 people but at the same time you are risking all of their family as well, when one person gets it, they infect others and those others infect others. Hence why we are in lockdown right now.
Well that can all be mitigated. Bigger problem might be lots of fans gathering wherever they can to watch it.
Dave has sky, lets all go round Daves. Oh Brian has BT pile in boys. Garry has covid pile in fellows. Er whoops
If they get it on free to air tv less risk of this, but where's the money coming from then?
