I mean the Larkin thing was just a bad dive and missed call, I can understand the frustration there.
But if Stamkos was out there quitting mid-play to complain to officials about a non-call, or showing visible frustrations with his teammates every time a play was botched, I'm sure that would be brought up. Or sulking/slamming his stick on the bench when a shift doesn't go as planned. But again, Kucherov does this far and away more than any other player on the team (or in the league, from what I have seen). It's not because of some anti-russian bias, he simply pouts on the ice and on the bench more than the other players BY FAR. His body language is absolutely terrible when he doesn't get his way, and this has been the case for quite a long time. On occasion I've seen Hedman get that way but nowhere near to the extent of Kucherov, and even he takes his lumps and manages to be effective.
Every player complains from time to time or yells at a teammate/coach, this Halpern incident could've been missed entirely and it wouldn't really change my perception on Kucherov's attitude. He's not the only player out there fighting through infractions, I don't see Point or Cirelli making a scene about it, they just keep playing like everyone else. Perhaps Halpern had enough of it too?
I'm not really critiquing his play, but I do question his long-term future with the team, especially if we don't land a cup in the next 1-2 years. Great player, maybe a great guy too but I have seen enough to think this type of attitude may wear thin down the road unless he can learn to fight through it and stay focused.
