Florida and Boston are both relatively top heavy now, and their success is derived from a fairly committed depth as well as a playstyle that leans on their strengths (also gaming the refs).
The Leafs are similarly configured, but plagued with generations of Leafiness. The last few games since the Devils wake-up call has been promising. Under Keefe, the Leafs have played what I would call aggressive puck possession -- a finesse style game that requires lots of puck holding and slowly picking apart seams in defensive structure. Mitch Marner exemplifies this playstyle. When it's on, it's on. The problem we've seen is come playoffs when space is at a premium and you have one dedicated opponent picking over your play patterns with a finetooth comb every day, and the refs call fewer of the body-positioning calls, this playstyle is just kind of easy to disrupt. The mental load and onus was placed on the offensive players to try to break down defenses and put in goals or else the team was dead in the water when we get burned on our own inevitable mistakes.
Prior to and after the Florida matchup, Keefe remarked about being more direct, pucks to the net, playoff style hockey. It's about time we made this adjustment. The Leafs are more patient and supportive of their flawed defense with forwards checking back responsibly, and it frees them up to capitalize on the other team's mistakes. Sort of like playing PK style the whole game. Save the aggressive puck possession for the power play. We can beat them with depth scoring if we adhere to a more conservative approach at 5v5, especially if there is no real need to stack line 1/2 to try to over power their matchups.
