I believe this year, more so than in years past, will be a much more offensive playoffs than we are accustomed to.
Boston doesn't have a shut down defensive corps. Krug, Hamilton, Bartowski, Chara are all offensively minded defensemen. Chara is also regarded as a defensive defenseman, but that's because of positioning and long reach. He has defensive holes that are becoming far more evident w/o Seidenberg in the lineup. They will rely a lot on Rask's play.
Pitt's defense is equally as holed. Problem with them is that Fleury is not as consistent as Rask. He can have severe meltdowns at times.
Philadelphia's defense is atrocious. They also have a journeyman goalie who may or may not show up on any given game.
Columbus has a few rookies and a few average-above average defensemen. They're physical, but much of their success is relying on Bob to show up.
Tampa Bay's defense is porous, but like several other team's i've just mentioned, their starting goalie - Ben Bishop, is an enigma to many offenses around the league.
Montreal's defense is nothing spectacular. They like to play a fast paced game that allows for many opportunities going both ways. Carey Price is relied on heavily there too.
Detroit is dealing with far more injuries this season than in years past. Without Howard, they likely wouldn't even be a playoff team.
It is conceivable, that the Rangers, with a new defensive style of hockey that is much more open than in years past, have a top 2 defense in the East. They have a top 3 goalie in the league. And they have a very balanced offense, if all players remain healthy/come back from injury.
I'm expecting a lot of higher scoring games this playoffs.
