Washington I believe went to far with the "defence" thing. So much so in turned the entire system from one extreme to the other. You can't go from a high power offence to a trap defence minded group and not expect to get killed and have to put the panic button down when you get behind.
Plus, Washington has sick depth....when they show up to play. A lot of their depth guys didn't did do anything, and guys like Semin scored the majority in the Rangers series. Backstrom was off in lala land. So then you start going down the line up. Green wasn't even a factor on the point, Knuble, Fehr and many other 2nd liners and down never stepped up, and it shows right here you can't just rely on Ovey to carry you through the playoffs. Washington is probably the new San Jose Sharks in that they just stopped giving a fuck about playing in the playoffs, and coasted it through thinking what they did before was good enough now.
