As far as football, wrestling or any other intense sport at the high-school or elementary school level, I think there is way too much emphasis on competition and not enough on skill development. At the early phases, such sports are supposed to be an outlet for kids to burn-off energy, build some muscle and skill -and socialize. Also, yes indeed, the coach and school administrators should be held responsible for pushing the team or individuals too hard. In the last two decades, TBI (Traumatic Brain Injury) is a well known issue -and there's no coach in this country who doesn't know about it.
Long before anyone knew what MMA (Mixed Martial Arts) was, I was in the thick of it back in the mid 80's. Everyone (that I knew of and worked with) trained with safety in mind. Did we push the envelope? Sure. Did we cross the line? No. Still though, there were always a few guys who wanted to go all the way and the allure of money and product endorsements etc pulled them in. We all knew what concussions do to you long term as we saw the effects on boxers over the last half-century. We watched old videos of boxers, BJJ and wrestlers. We studied their moves over and over and we followed their careers for years. -And we saw them get dulled, dumber and more crippled as the years passed. -Yet some people conveniently forget all that when money talks.
Maybe some of the early NFL players didn't think about concussions but, ANYONE involved in any level of sports since the late 80's knows about it and talks about it every day. By the time you get into college or pro leagues, I think you're on you're own. The people who get into this at the advanced levels know what they're doing and they know the risks. -No doubt about it and I'm speaking from first-hand experience.
