Watched the game on the Columbus feed last-night and during the pre-game Jody Shelly kept emphasizing for the blue jackets to attack the Bruins from behind the net and then reiterated it just before the start of the game as in to watch for the blue Jackets to set-up in Gretzky's office.
This tells me going in the Blue jackets had found an area of where they felt there was a weakness in attacking the bruins down low, as through out the game they used a triangle down-low, with one of them presumably always being behind the bruins net and it did seem to create someone being open in front and it help lead to 3 blue-jackets goals.
This could of been just coincidentally as its something the Jackets may have been working on in practice or they did see a weakness in the Bruins defensive coverage before the game, which resulted in this. Either way its something the Bruins need to shore -up as they were exposed.
With this in note, I'm not to overly worried as the Bruins have the personal/talent/coaching, to make the changes and if they were exposed to a gaff in their coverage its better now than in the playoffs.
I'm also am not overly worked up over this loss, Bruins went in very short-handed and the Jackets are literally fighting for the playoff life's and their coaching staff for their jobs. On top of that they are a very strong team, who themselves could make a long playoff run.
