That has been a common theme for these playoffs in my opinion. With few exceptions, the Ducks have beaten themselves when they have lost.
It's not to take credit from the other team, be it the Oilers or Preds in Game 1, I believe your opponent gets credit for forcing you into sloppy play. With that said I feel the Ducks have had a higher percentage of defensive breakdowns turn into a goal against. When they clean that stuff up they look like they can beat anyone.
Goal #1: Montour joins the rush - no problem. Cogliano and Lindholm somehow do not recognize this. Just brutal.
Goal #2: Gibson just SPACES out. Vatanen (or Manson?) decides to not beat the s* out of Arvidsson for standing in the crease. Again, beer league.
Goal #3: Silfverberg makes a TERRIBLE pass. Gibson overplays Arvidsson and is left swimming. Theodore decides Arvidsson - BEHIND THE NET - is more dangerous than THE PUCK coming out into the crease. Getzlaf does not pick up Forsberg, which he could have by moving his feet. When you get 4 out of 6 guys on the ice boning it, you know you are definitely DOING IT WRONG!!!!!
