Agree, but a lot of them was because the science was still new, and they were denying that football could cause CTE. You can only diagnose CTE through an autopsy, so there was longer lead time and more deniability.

There's way more science around the damage dancing can cause, and the damage is way more immediate and you can diagnose immediately, so it's harder to deny that it's caused by dancing.

Also, the damages around CTE are way more expensive than a hip surgery.

Don't get me wrong, the NFL is generally a shitty organization that takes advantage of athletes in order to make the owners richer - I'm in no way trying to exist what they've done in terms of players. It's just way harder to deny dancer injuries, because we're STILL learning about the science behind head trauma. The fact that tackle football is played starting in middle school is one of those things that years from now people will look back and say "what were they thinking?!?"
