It's a grey area, but the biggest things that stick out is the huge gulf in popularity between football and fight sports in terms of how many kids participate in each sport, and the NFL's lying, feet-dragging, covering-up, not taking good care of retired players-way of approaching this issue. Like, nobody's ever pretended like boxing wasn't horsefeathering you up. The NFL, however, kept pretending that even as guys just get bigger and faster and all they're wearing are these dinky helmets (nevermind concussions don't just occur due to head impact) that things like concussions and CTE and brain trauma weren't a major problem. I mean, call it hypocrisy if you want, but boxing has worn its scumbaggery in how its run and promoted and what it does to the fighters almost as an odd badge of pride for its entire existence. The NFL, however, for at least the last 25 years, has tried its hardest to present itself as THE all-American sport, embracing jingo-istic pro-military/pro-'Murrica garbage, all the while trying to tap dance away from things like concussions and CTE and what players are doing off the field. This is not the kind of sport and not the kind of organization that should be inspiring who knows how many kids each year to be colliding into each other with all the safety precautions of duct-taping someone to a car seat if the seat belt is broken. Like, don't think this means other sports don't have to deal with concussions; they all do. As the understanding of how the brain works has evolved, it's become clear that just sudden stops and falls can cause brain injury even if the head doesn't seem to have been struck, or hasn't been struck hard. But it's the height of absurdity that football, where they've been intentionally working to make these guys as strong and as fast as possible, ran around as long as they did with their fingers in their ears (and still are, to a degree) about the issue. Nobody's thinking you can completely prevent brain injuries in sports, but football is barreling towards a brick wall. Something has to change. For sure. I agree with all of that. The NFL is horsefeathering horrible. And the worst part about it is, as you said, the NFL spending decades lying about it and covering it up, when they could have been working on finding a way to change. I'm not sure how much it will even help, but new technology could help some, particularly as it pertains to the football helmet. And they wasted decades of research. They are the Big Tobacco of sports.
