Growing up and playing ball in Miami, we were never allowed to have water during practices. Never. None of us died. As a matter of fact, I never saw anyone cramp up either. Not saying it was right or wrong, but that's the way it was in high school back then. Now we preach hydration to players and they're cramping all the time. Can't really explain why. Perhaps we were outside more on a regular basis and were more used to the heat. I don't know. We tell our players now to drink a minimum of 1 gallon of water per day during school hours. Then also drink at practice and following practice yet kids still cramp in August and September.
