Any team can play like Boston. Line 4 guys up at your blue line and keep your stick in the middle of the ice. Offensively they've shown me nothing. They get some odd man breaks from their lining 4 guys up approach that gives them some chances. Otherwise it's dump the puck in get it, pass it to the point, shoot and hope for a bounce. There is no skill there. That team has some players with skill, they rarely ever use it.
Any team can do what they are doing. They certainly aren't the most skilled team in the league. They have a lot of good players and are pretty balanced, but there isn't anything special about that team. Really their PK is the reason they are where they are. If a team could score on them on the pp and get the lead, their line 4 guys up at the blue line approach isn't going to look so hot and the fact that they aren't very good offensively will shine through. To me other than game 2, this was the biggest problem the Pens had. They get some power play goals, they win that series. It changes everything Boston was and is still doing. Teams haven't been able to get the lead against them though.
The other issue the Pens had in that series is they completely stopped going to the net. Their center drive was completely gone. I taped game 4 and watched it a few days later due to being in a wedding. I already knew they lost, so I paid more attention to why they weren't generating any offense. It was awful to watch them enter the zone when they were actually able to carry the puck in, drop the puck back to the forward slightly behind them and then simply coast waiting for a pass back instead of going hard to the net opening room for the guy with the puck. They did it over and over and over. Get into the offensive zone and just coast waiting for a return pass to one timer, meanwhile the Bruins D just stands there right beside both forwards. No wonder they couldn't score.
