I played hockey on my high school team and a travel team my senior year in high school and worked 35 hours a week.
Talked to some of the kids currently on the team now at our alumni game and high school hockey has become almost a full time job for them. On ice practice 3 times a week, off ice training 4, and at least 1 game a weekend. It's insane how much time is put into youth sports nowadays, and I'm not that far removed (7 years).
