"No good deed goes unpunished" - Oscar Wilde
Before you do anything make sure you can be insured adequately for managing a team or having event insurance. Years ago, I used to manage and coach and I know insurance was part of the gig. At that time, I was concerned about teeth, concussions, etc... Today, you have much bigger issues with a virus that has the potential to kill people. You don't want to be in a position where you are responsible for others irresponsibility especially around Covid-19. Before doing anything associated with players and parents, I would talk to the insurance carriers to make sure you can be covered and what those details include and not include.
As always, JMO.
