It all seems like it is going to be a calculation of risk. These risk calculations are made all the time. Any time an athlete steps onto the field, court, diamond, etc. there is always risk involved. It's how the adults in the room decide to mitigate that risk that is at play right now.
A football player can tackle the wrong way and get a concussion. A female soccer player can turn the wrong way and tear her ACL. The answer to these kinds of things has been risk mitigation through training coaches (Heads Up Football etc.) or through specific strengthening exercises that help with prevention of ACL tears.
We also have a precedent to cancel contests completely or to reschedule them when there is too much risk. If there is a storm in the area that includes lightning the field and stands are immediately evacuated due to the risk presented. Teams have to wait 30 minutes past the last lightning strike to continue the game. Sometimes the games are postponed. Sometimes they are canceled completely.
Same for baseball and softball games being played at schools with no lighting systems. At a certain point in the contest if it is too dark the game is called or moved to the next day because of unsafe playing conditions.
This will most likely play out the same way. How much risk is involved in playing high school sports this year? Can the contests be played safely? Do all parents and athletes need to sign a waiver absolving school divisions of liability should something happen? Is that even legal?
I think it goes without saying that everyone wants to get back to normal. We all want high school football, cross country, volleyball, golf, etc. We want the kids to have these experiences and to do so safely.
The VHSL and school divisions across the country are going to have some very tough decisions to make about school and sports this year.
