The caps could score other ways on the pp too. They had constant movement and clean crisp passes they would cycle it so well that the pk unit would shift and collapse leaving over open. We forced the one time option and allowed pk units to keep formation we have to work on getting other teams to collapse more trying to work it inside close to the net from the corners it will end up leaving the point man open with more time and space rather than them getting it at the blue line being forced into an escape move scrambling to keep possession.
This^^.
Ovechking would get one PP goal every 3 or 4 games, and yet the Caps PP was cooking at close to 30% in some of his most productive PP seasons. They usually weren't just solely feeding him the puck the way the Sabres tried to feed Tage last season, and in the games where they did recently, (trying to get him the goal record), it rarely worked.
I would also add that NHL powerplays have evolved substantially in the past decade. The days of teams puck chasing and hoping to outwork the execution of the opponents powerplay on the PK are dead. Maintaining formation and keeping the passing lanes closed is the new pk gold standard, which makes the "Ovechkin one timer powerplay strategy" a lot tougher in today's NHL.
While Appert didn't lay out the PP plan with a ton of verbiage, the inclusion of no more "standing on the dot" and "tired chaotic PK" should be pretty clear that skating and movement will be a priority on the PP, and the days of Ellis' static formation should be gone (hopefully to never return).
