There's a HUGE difference between football gear in the heat and baseball gear in the heat. I think that the big boys on the line during football season are more susceptible to heat-related injury as well. I played all of my high school sports in a so-called "temperate" climate, similar to N.Kentucky, and after a couple of practices in the heat you could cope. Eight years in the Marine Corps taught me that it takes a solid week to acclimatize to any new "situation".....whether it's hot,cold,humid,arid,high-altitude,low-altitude. Most Marines can do a 20mile hump in their sleep. Add a flak jacket,helmet, and so-called "lightweight" battle rifle to the mix and it's fun time. Add a 60 pound pack and it's something that they never forget having to do. My best advice is to keep them hydrated coaches. From all of the baseball that I've seen at Freedom Field(If that's what it's called these days) the players are in more danger from the turf.......slide early, gentlemen. That turf is like a slip n" slide, and those bases don't give.
