The NCAA abandoned it in 1960. There appear to be two intercollegiate boxing organizations (National Collegiate Boxing Association and US Intercollegiate Boxing Association) currently active.
Little-known fact: boxing is the only sport specified by name where if a California high school competes in an interscholastic (as opposed to intramural) event, the school can be banned from all state championship tournaments in all sports for a year.
You can only assume risks you are aware of. Since the dangers of repeated concussions were not well known until recently the players did not assume those risks. However, the teams did not know about the risks either so there is no reason for them to take on the risks now. Unless the NFL knew about risks earlier than everyone else and it was hiding that knowledge there should be no basis for suing them.
The risks of playing football are generally overstated, ex-NFL players live longer than average and commit suicide at a lower rate.
Plus they get to be famous, rich, and to play football for a living.
Who knew it would be dangerous for two 250lb+ people to repeatedly slam together at 15MPH?
Torn ACLs, sure. Early onset dementia, not so much.
To repeat what has been said above:
From the above collision, I’d expect to assume a risk of broken bones, ruptured internal organs, paralysis and possibly death.
Until the last several years, however, I would not have expected to suffer long-term, cumulative brain damage. If the NFL, NCAA and other organizing/sanctioning bodies knew about that danger prior to that time (and the evidence is pretty strong they did), yeah, sue their asses.
Way to summarize a complex situation into a sound bite.
Football has two big concerns facing it, though I don’t know which is the bigger threat. First, a growing number of parents are putting the brakes on participation by their kids. Despite the largest number of high school students in the country’s history, high school participation is down about 1% overall; it’s up in the Deep South but down sharply in California, Arizona and a few of the northern states. A small negative trend, to be sure, but I think it will continue.
The second issue is insurance. As lawsuits become more numerous and awards larger, the insurance companies will continue to raise premiums or simply pull the plug on coverage. I can’t imagine a high school district would dare to take on the risk by itself.
