A couple late thoughts on the recent stick incidents:
Trouba hooks Frederic's arm as Frederic tries to go around him. Frederic then probably grabs Trouba's stick (you can't see for sure on the replays). Seems like the natural reaction when someone is holding your stick is to try to pull the stick away in the opposite direction of the player holding it. That's not what Trouba did. It looks to me like Trouba meant to hit Frederic with his stick, perhaps thinking he could use the stick hold as an excuse for the swing. Kind of like when a basketball player holding the ball in both hands pivots and intentionally nails an opposing player in the head with his elbow, thinking he can get away with it because he has the ball.
Smith should have been suspended, you can't not punish a two handed swing at a player like that. But at most, 1 game more than whatever you give Konecny as I'd argue that Konecny's hit was actually more dangerous. It's hard not to view an egregious foul such as Smith's as unacceptable, but in this case I'm glad he did it. Maybe if more players reacted the way Smith did the league would finally crack down and eliminate dangerous actions such as Konecny's. If it wasn't the playoffs, I'd have taken a 2 game suspension if a bottom six Cane had wound up and taken a 2 handed swing on Matt Martin after he gave Staal a cross check in the back away and then knelt on him after he went down last year.
Note that my goal isn't retribution, it's to force the league and refs to control that shit so players won't get hurt, either from the initial foul or the response.
