How people think a PP QB is the solution to our PP problems is beyond me. Sedin's run the first powerplay unit and the 2nd unit doesn't matter.
I really hope this is sarcasm, but the 2nd unit definitely matters- ESPECIALLY on our team. The reason that the 2nd unit matters is because
the 2nd unit has to protect the 1st unit. Imagine if the Sedins are in the middle of a very long shift where they've played in the offensive zone for about 1:30 and probably need a good rest.. then, the defending team would not have to worry as much about taking a penalty because they know that 1) the 2nd unit is useless and 2) that the Sedins will still be tired for their next shift.
The idea of protecting your best player is a concept common to every single sport. The 4th batter (in this case, 1st unit PP) on most baseball teams is the best batter on the team. The 5th batter, (in this case, the 2nd unit PP) must be good so that the pitcher (defending team) can't pitch around / walk / play too aggressively (commit a penalty in the middle of a long Sedin shift, play the Sedins over aggressively, only having to worry about playing the PK for 1 minute) against the best player.
The Sedins are not out for 2 minutes every powerplay. They are out for about 1:10, unless they have a good shift, in which case they'll have about 1:30. Unfortunately, the reason that the 2nd PP unit doesn't do so well is because the PP is so focused on making the Sedins produce.
How many times does the first unit come out regardless of how recent the last Sedin shift was? How many times does the 2nd unit only come out after 1:20 of the PP is gone? The 2nd unit is struggling because as soon as they set up, they usually only have about 20 seconds on the PP. Yes, we have to give prime minutes to the first unit, but the second unit has to be given some time to produce because it's essential for the 2nd unit to produce.
