The umbrella just works so well with the personnel Montreal has. You have Gallagher in front of the net causing a ruckus and Pacioretty in the high slot to pop in and out for shots and Markov/Chuck on the boards to control the play and draw the box to collapse with Subban on the point for howitzers.
This is the exact PP the team ran when they were consistently 1st or 2nd in the NHL and for the life of me I cannot understand why they went away from it. It's not like the other teams figured out how to stop it. You can't stop it when it's perfectly ideal for the players you have.
Coaching can't really be that hard, they're professionals just put them in the ideal position and sit back.
19th last year and what looked to be 30th pre season.
Not going to be as simple as that.
