I’ve been looking. Child transmission at indoor basketball games. Outdoor adult transmission at a golf tournament.Can someone post a link to one article that shows a childs covid-19 death from participating in youth sports?
I cannot find evidence of outdoor child transmission.
Georgia tech has a calculator for finding the odds of at least one person at a gathering currently having covid.

COVID-19 Event Risk Assessment Planning Tool
covid19risk.biosci.gatech.edu
It shows a 5v5 game as 29% risk for LA. 58% for 11v11. (10 people versus 25 people)
I’m letting that drop a bit more before joining the folks doing independent scrimmages. Even then, the plan is to keep it small and the have the same people every time.
