I think it’s confidence and determination to get better, don’t see him being cocky. He never puts himself above his team, he works hard, and he is always congratulating teammates and is happy when they score and whatnot. He has tweeted good luck tweets to all his Team USA buds who have started their first NHL game.
That Interview during the Worlds, felt more of a confidence booster for his entire team. I read it as hey my team is good and think we can test their goalie. I think it’s more of a leadership thing and raising morale for his team. I don’t see it as hey you are beneath us and we will win. He has respect for the opponents he plays.
One thing that stood out for me and this is minor but him rushing back to break up a play, or going to the boards to help aid a line mate. Other players may not want to get dirty, he has no problem doing that. To me that is what will make him a better complete overall player. Points will come but I like when he does all the little things. Comtois has been doing that as well when he is on his game.
