The powerplay for the caps works so well because they utilize the bumper position to it's fullest potential. You can't just cover Ovi, because that's not actually the most dangerous shot. The biggest threat comes from the bumper and if you don't play it right, it's a point blank shot.
Rangers utilize Kreider in front of the net, which is fine, but if Zibanejad is going to attempt to play that bumper position, then Kreider has to move away from the front of the net and back off to the side to be open for passes coming down low, that means Strome needs to back his butt up closer to the boards for Kreider to have an outlet for when Zibanejad isn't open, otherwise possession is lost on a turnover. With Kreider and Zibby right next to each other, you basically have 1 player easily covering 2 NYR players. Kreider needs to play a position that goes back and forth to the front of the net depending on where the play is at.
First line isn't working. Last night Gallant said he doesn't like to change it up but the changes "worked". If he continues to roll the first and second line, they better find a way to produce and carry play or this is going to be tough to watch 2-25 games in.
