I'm pretty impressed by Mack's improved calm and maturity in these playoffs. Despite his numbers, I don't think he had as many dominating shifts per game as he is used to. Usually, that leads to him showing signs of impatience, trying too much to force plays, which lead to mistakes. This year, against Win especially, I felt like he stuck to the game plan, dumped the puck more and stayed calm, showed less signs of frustration no matter what. And it lead to good results and good leadership. That's very good news for tight games.
