Thinking after that showing, this team needs everyone playing with intensity. Guys with legs that can move the puck.
Marchand - Bergeron - Pasta
DeBrusk - Krejci - Kase
Kuraly - Coyle - Stud/Kuhlman/Bjork
Nordstrom - Wagner - Clifton
McAvoy - Gryz
Krug - Carlo
Clifton/Chara - Lauzon
I know this will not happen, but I wish the Bruins could limit Chara's ice time to mostly PK minutes, and keep him fresh for the 3rd period if the Bruins are up. Clifton taking shifts on the 4th line, I think could work, and if the Bruins are down or tied in the 3rd, bring Clifton down with Lauzon, and cut Chara's minutes to only PK minutes. Playing Chara when they need goals, doesn't seem right, and making McAvoy play with him, think kills his game when it's top level team's they're going up against.
And Stud or Kuhlman with Coyle. I'd try Stud game 4. Win or lose, judge him on his individual game and if he doesn't seem up to the task, I'd go Kuhlman before Bjork here game 5.
What actual lineup will be scares me. Think Cassidy seems overwhelmed and it's messing his ability to make decisions.
