Pardon if this is not a fresh take but in some ways concussions in high level athletics is like a male-dominated version of the #MeToo (not to say either situation is restricted only to a certain sex).
Basically, people who aren’t in it or don’t have to deal with it...the lay person...thinks to themselves “how could you not know...how could you not say anything...how could you just go along with it...etc, etc”.
But it’s about more than that, it’s about a deeply, deeply instilled culture of how things are done, how people should behave. It’s about livelihoods and dreams and aspirations and everything that makes people feel valued and worthwhile. To distill it to “getting hit in the head feels bad, you should stop” is simply missing the point.
Thankfully, research has advanced and people speaking out are making a difference. Things are changing and will continue to change - much the chagrin of “old timer fans” who miss how great everything was back in the day and who don’t have to spend their lives worrying about why they feel the urge to kill themselves on a daily basis.
