i've seen this opinion come up quite a few times in the last few years. some small % of American football fans have a similar idea; go back to leather helmets, and the big hits led by heads will surely stop after a few guys KTFO themselves.
i don't want to debate the idea, but it did made me wonder; has any sport ever taken away a safety precaution for the sole purpose of making it so much more dangerous that the athletes will stop doing whatever it was they were doing, after a few of their brethren have died?
so i'm not critiquing your idea or debating you. i'm just segueing off it. hell, if we can come up with examples, we can strengthen your opinion.
