Not a fan of Trouba, but that's just a clean old-school type hit. We don't see that hardly ever anymore.
For those of you who didn't see the old NHL, back in the day a forward had to have some caution, as every team had at least one D looking to blow someone up like that coming over the blue line. It used to be the rule was to play the body, like Trouba did, now they play the puck. So whenever someone talks about McDavid being the best ever, consider that he doesn't have a Darius Kasparitus or Scott Stevens waiting for him to cross the blue line. And if you think star players weren't targeted, Darius targeted Mario Lemieux, and Steven's targeted anyone he could line-up, notably, Eric Lindros and Paul Kariya.
Great hit.
