Skjei absolutely makes more sense from a skill perspective, but they are super committed to having a RHD in that slot. Under Rod, the only left handed D with serious PP minutes are Slavin and Gardiner. The others are Faulk, Hamilton, DeAngelo, Burns, Pesce. Even Joey Keane, an RHD, came in for a one-game cameo and got almost 3 minutes of PP time.
If we cornered Rod and forced a full explanation, I expect it would be along the lines that we want a shooting threat toward the center of the net from that left point position. That draws the PK’s high forward toward the middle, which leaves a bunch of space for a left handed forward to create a shooting threat on the right side of the ice, and as the puck rotates lower that forward can slip in quietly as the uncovered shooter.
If you watch the PPG Pacioretty scored in this game, that is exactly what happened. CBJ swarmed all over Burns and Aho on the left side of the ice, so Pacioretty had plenty of space to sneak in an open one-timer. Three quick passes and it’s a slam dunk goal.
The problem with having a LHD in that role is that the D doesn’t need to respect that inside threat as much, and his passes to the left side are going to be a little more awkward and take a little more time. Unless of course you have him at the right point, in which case you’re looking at switching the forwards around as well.
