I don't buy the "too cute" line.
The Bruins stuck to the system for the first two periods....they expended a lot of energy forechecking and did a good job of causing turnovers in the neutral zone, but it is too easy to defend against them because they don't attack with speed, how can you attack with speed when you are only using part of the ice? and part of the reason for that is that Julien dresses his 4 stay at home defensemen.
The system allows almost no individual initiative with the puck. If you watch other teams, the players (even defensemen) are given more latitude to make plays. For example in the Rangers game Klein, who is by no means an offensive defenseman, was swaggering around with the puck because he has confidence/permission to make plays. On the Bruins defense Krug has been given the green light...that seems clear...but the other guys (due to lineup choice and system by Julien) aren't contributing to the offense...they generally don't transition well...again that's part personnel and part lineup choice by Julien.
So of course the meat and potatoes...win the puck on the forecheck...move it back to the point....win the battle for position in front of the net. You should be doing that with a bunch of heavy/physical guys that this team doesn't have.
And then the coach says they are too cute. Well you don't want skilled players like Krejci, Pastrnak, Smith, Soderberg, Eriksson, Marchand actually trying to make plays with the puck? Look at the ice time for the forwards last night, you want these guys (sans Marchand) battling on the boards the whole night with big strong men like Johansen, Hartnell, Foligno, Dubinsky? I give the Bruins forwards credit over the last several games since the Jacobs statement, they are back competing hard especially Lucic, but I don't believe this kind of play suits them.
