I'm not sure what age group your kids play but at what point are you worried about your kids getting burnt out? Playing 6-8 tournaments, 8-10 league games, summer futsal, winter futsal, camps...
I've been coaching older players for several years now and the amount of kids that get to their junior/senior year and are burnt out is alarming. I've seen so many kids lose the love of the game because it's been forced down their throat for so many years.
I think clubs are so scared that kids are going to leave and go to another one that they try to keep them busy and committed all year round instead of letting them be kids.
I've heard so many parents talk about how tired they are from all the time and travel....I wonder if they have stopped to think about how their kid feels?
Just my 2 cents.
Have two sons. First one tried a bunch of sports but did not like competition nor contact. Joined the band. Great kid with great grades.
Second one has loved soccer from the beginning, but we take the summer off. Winter, he has his choice, plays futsal but no practice, just the games. Wanted to play basketball this winter.
Used to coach HS many years ago, and I too have seen really good players walk away from the game. it wasn't fun anymore.
