I coach U8 football and DS also players rugby. They’re incredibly different- football is proper teams, organised matches and very formal. The party line is it’s non competitive but in reality you’re grouped in divisions and everyone including the kids know which is the top/bottom division.
Rugby is much more relaxed, lots of rolling subs, no keeping score and a coach referees it. Personally I think the over formalising of football does no favours as it’s taken too seriously.
The parents are the biggest source of hassle for all coaches. I’m a parent who’s volunteering and I constantly think about quitting to escape the abuse and hassle.
