Edler on the right side on the PP forces him to play the puck on his backhand when it comes around the boards. He clearly isn't used to this, and is often bobbling the puck on his backhand or trying to play the puck with his skate. Switch him to the left side on the 2nd PP unit. He seems apprehensive to shoot, and this may be because he's worried about giving up puck possession when he's on the ice with the Sedins. Let him play on the second unit where he might not feel as much pressure to get the Sedins the puck.
Agreed with this, and on that note I want to point out that I don't like Daniel on the point. He doesn't have a nearly threatening enough shot to be effective from there and he's not a powerplay quarterback either so his playmaking abilities aren't really being put to the best use in that position. I'd like to see Daniel down low on the right side, where he's on his off wing and can easily score those nice tap-ins, and Kesler on the point on the right side, which would allow Edler to go back to his normal position on the left side. Put Kassian down low as the net presence and then I think you'd have the perfect PP set-up.
Kassian - H. Sedin - D. Sedin
Edler - Kesler
Anyway, carry on with the Edler discussion.
