I think you're right in that teams need to think about it. I have no issues with playing tournaments in summer or hot weather, some of my kids best games and training sessions have been in summer when there's no school, they have time to sleep during the week and recover, and the game is more fun when the stress of school is not there. I don't really understand how any team can get excited by Slammers marketing for a Norco tournament in summer, though. It just doesn't make any sense, and all involved have to consider why they would get themselves into something like that in the first place. When I looked on the schedule I didn't see any games on turf, that could've changed, but that's a good sign, and a heatwave this weekend is more bad luck than anything. The weekend before wasn't that hot.
