lot of people Suddenly Jibing Pete in here I see. Sestito and Janssen sucks, but it is really nothing compared to the horrible power play, where the puck movement and the players are far too slow. I don't see what fixes that. I think they had 1 shot on 3 power plays which is unacceptable.
Bottom lines get fixed somewhat when they realize Janssen isn't needed anymore, although realizing that about Gionta will take much longer, I fear (and indeed may take just Lou not re-signing him after this year). Still, your 4th line is largely unimportant - at least this year the Devils have 9 forwards they like playing, not 7 like at some portions of 2011-12.
As for 2 goals, the Devils have to be getting points when they score 2 goals a large portion of the time. Like 70% of the time when they score 2 goals in regulation they should be getting at least 1 point. They're not a historically great defense but they are close. But Brodeur has lost his last 4 starts and Schneider has won his last 3 - I believe the idea that Brodeur just wins and that Schneider doesn't has been retired.
