I am no fan of the "Collapsing 4 Man Box". I Bet you there are not many Goalies out there that Love this system. Everyone winds up on the doorstep of the Goalie unless the right Shooter picks the corner first....
This Pk is an adjustment to the I-formation/diamond hybrid they were playing last year, which they were executing poorly. (Other teams run that system with a fairly aggressive style too. NYI don't have the players for it).
In my view, you tip your cap to Utah on the first PP goal. First you had the Cooley saucer/skip pass across the ice then a fast perfectly weighted bit of sauce from Macelli to Crouse. There was a stick down in the lane, but those two perfect passes which beat the PK. It happens. That was amazing PP execution. If the criticism of the diamond is that it leaves the slot open after a skip pass, fine. For me, it's a tactical choice, and getting beat by an opponent skillfully attacking a weakness isn't something to dwell until it becomes a pattern.
The second PP goal had three players with their eye on the puck while 2 had no idea what their assignment was. There was no skip pass to get the whole unit moving to set up a seam pass. There was no stick in the lane, and nobody covering the slot. There's no excuse for both failures. That was Cizikas/MaClean, and it was every bit as bad as Dobson's blunder.
Is it possible to take a timeout after scoring a goal? If it's not against the rules, it would have be good to take a TO there after scoring to put the team ahead. Absolutely cannot have giving up a quickie after scoring become a thing, and there would be no reason not to take the TO with a minute or two left in regulation.
