I think Mikko's combination of size and skill could make him the best player in this series. Arizona will try and shut down Nate's transition game, but Mikko does a lot of his best work in the O zone. He's the only one with a point per game against them too.
I can see Girard having a good series too, though he hasn't been very productive against them. Makar will get a lot of focus from Arizona, and the coaches will be pushing G to keep moving his feet up ice to break Arizona's netural zone forecheck. We may see a lot of Sammy with his dancing shoes on.
Also, Calvert's 5 goals are the 2nd most he has against any team in the league, behind Pittsburgh (6). Teams lean on him and his hard working style to get the greasy goals against teams like Arizona, so look for him to be a factor.
Nate actually has a hard time scoring goals against Arizona.
Here's everyone's splits:
MacK - 19 games - 3 goals 13 assists - 16 points
Landy - 25 games - 8 goals 8 assists - 16 points
Mikko - 9 games - 3 goals 6 assists - 9 points
Kadri - 14 games - 3 goals 4 assists - 7 points
Makar - 2 games - 0 goals 2 assists - 2 points
Girard - 8 games - 0 goals 1 assist - 1 point
Calvert - 19 games - 5 goals 1 assist - 6 points
