Ok I got a little carried away with the whimps comment. Not to undermine the deaths with is as absolute tragedy but in most all cases it's a preexisting medical condition or some type of medication or stimulant which is the root cause. Let's just agree to disagree.
Down south they don't have such rules because they would never get any practice or games in. I understand it has good intentions but it's crazy to call a game because it's too hot, simply add more water breaks. We wonder why kids are turning into whimps these days.
