Lol, no one wants Trouba to hurt himself. I can remove the player from his personality very easily. But his opinion on the matter will be looked at as funny with the way he plays. That's the whole thing that people are confused about. You can't say you care about mental health of players/athletes and then go out and level them with NHL 24 type hits.
The point I was making is that it seems possible though no evidence behind it that he was speaking from experience. There's conjecture it might be Miller's experience and in that case fine laugh away. But there's a possibility it's his. And if that's the case posts like the ones made in this thread are inappropriate.
