I gave you a short list of the numerous hits like this. What are you on about? All of those guys except Athanasiou I think missed at least a game with a concussion
Kharia was stretched out and missed months. Jarvis I think was their final game, but there's quotes from him saying he only remembered fragments of that game and the next day a few weeks later.
A few of those are 21-22 where I recall people tallying like 5-6 that season & playoffs alone. This playoff he seemed to miss on clearly attempted headshots. You seem to not want to call it a headshot if it's a legal "good hit" as you say. He time after time sees guys in positions he can get away with the hit on, he goes for it. There's no rational way you can say with a benefit of the doubt he isn't going for their heads.
Cte doesn't come from just concussions, but hits over time to the head. So I don't know what you're trying to single out. Trouba knows what he is doing on thr ice. He might be a great guy off the ice, but his repeated actions earn him ill will.
Kharia missed exactly one month, was not diagnosed with a concussion, and went on to opt for lower back surgery (which had nothing to do with any injury sustained from the Trouba hit), and missed the rest of the year due to surgery.
Crosby not only didn't suffer a concussion from the Trouba hit, Trouba wasn't even suspended. It was a clean but hard hit.
Dorofeyev missed limited time but also did not suffer a concussion.
Athanasiou, also no injuries.
Jarvis is the only player to date who has suffered a concussion from a Trouba hit.
If you're making the "any trauma to the head can cause CTE" argument, then by all means, tell these fully fledged adults who have all the medical information and education on CTE available, who play a game involving hits on a hard ice surface at breakneck speed against other humans that average over 6 feet 200 pounds, that they should probably retire to mitigate the risk. Because you absolutely cannot play the game of hockey and avoid incidental head contact.
Here's another fact that'll rock your worlds: you can suffer brain damage from a perfectly legal but hard hit shoulder to shoulder! Your head doesn't even need to be targeted. You can also get brain damage from falling hard. Any hard hit to the body can shake the head and cause a concussion or long term brain injuries.
The obsession with CTE among fans of a rough, physical sport is becoming a meaningless virtue signal. It was once a crisis, before players had the information/education, weren't paid well, and routinely participated in overtly dangerous plays beyond anything we see in the game now.
All of those factors have been corrected. The game is a fraction as dangerous as it was in the 70s-90s. The equipment is far and away better. Everyone is educated on CTE. Concussion protocols are standard, in-game. The salaries ensure that even league minimum are wealthy men, and the health and benefits fund is substantial.
We can all calm down about CTE. The risk is maximally mitigated, as much as it can be without compromising the nature of the game.
But because so many fans want that virtue signal talking point, EVERY hard hit gets its own forum or twitter thread with people declaring the offending player to be a headhunting concussion monster. Even when - surprise! - there was no significant injury, and no suspension from Player Safety.
Yes, Trouba lays big scary hits. No, that doesn't make him the lifetime recipient of the Scott Stevens Your Career Is Over Enjoy Hospital Food Award.
