I don't know why you're blaming pluggers or top 6 bottom 6 vs top 9 bottom 3 when the Jets PP was neutralized by the Leafs PK.
Laine, Byfuglien, Scheifele, Ehlers, Myers, Little, Trouba etc all played anywhere between 7-10 mins of the game on the PP. They failed to get a single goal on it.
What else can Maurice do besides put his best players on the ice for the PP? He can't get on the ice and score PP's for Winnipeg. Their PP was horrendous...everyone just stood around waiting for the puck with very little movement.
Winnipeg does not have the depth right now to play a top 9 bottom 3 system. They have to stack their lineup to win otherwise you will end up with three average lines.
There is a whole lot wrong with this.
To start, who implements the PP systems? If you think they're standing around too much, that's on the coaching staff. They also have a PP1 that's designed to stand around (Laine, Buff, Lowry) and that only has 2 players that know how to do zone entries (Scheif, Laine) when our players that promote the most movement on the PP (Ehlers, Petan, Morrissey, Perreault) are either on the 2nd unit or not on it at all. Also, the players that are best on zone entry (Petan, Perreault, Morrissey) are not on PP1, or again, not on the PP at all. Who's that on?
Next, they absolutely have the depth to play top 9 bottom 3.
Ehlers-Scheifele-Laine
Connor-Little-Wheeler
Any combination of Perreault, Petan, Copp, Armia, and Dano is a competent third line.
Also I wouldn't say their PP was "horrendous", there were plenty of great chances that could have easily gone in, they just didn't. Lowry had 2 point blank, Laine had a great chance on the first one. 20(?) shots, 2 of those go and suddenly we're at 25% and it was a successful PP game.
