Can`t get the puck to Connor through Morrissey ALL the time. Scheifele has to create some pressure on the other side, with the help of Wheeler and even Nino - and then one of Scheifele or Wheeler have to be able to get the puck over to Connor quickly for the kill shot. This way the goalie is moving across his crease and is much more vulnerable.
Think of the Capitals PP but simply reversed with Ovi situated on the left for the kill shot. All the set up work occurs on the right side through Backstrom, leaving Carlson at the blueline as a secondary threat.
Problem is we again have Scheifele/Wheeler either simply playing catch with one another far back near the walls, or, holding the puck much too long and wishfully trying to create passing lanes by way of wasted stickwork. No pressure created.
