I'm going to hop on my soap box and go off on a side tangent.
People that say "my kids will never......" usually feel that way b/c they played that sport and made poor choices w/ their bodies (being head hunters in football, extreme weight cutting, etc" or had over bearing parents.
I wrestled and played football, was a D-1 prospect in both, and still love both sports. Neither of parents were athletes and were clueless and I wrestled HWT so I only had to cut weight my senior year and some during my Cadet freestyle days when the limit was 242. So I had very few "bad" experiences outside of pressures I put on myself.
However I know a guy who knows a guy who has a friend that was a top notch wrestler, but made very poor choices, he cut extreme amounts of weight b/c it was the cool thing to do, wrestled on a torn up knee b/c it made him manly, had an over bearing father, and allowed the sport to beat him up, so now he will not let any of kids wrestle b/c of "The sport beat my body up and spit me out. My kids will never go through that" The sport didn't beat him up, his outside influences did, it's all about learning from mistakes and educating.
Same with football, If you have proper technique and try not to be a meat head you'll be fine. People that feel bad about football and will never let their kids play usually feel that way b/c of poor choices that they made, not what the sport did to them.
