They'll be expecting a tougher game from the Blues, and probably will expect to get fewer calls and power plays than they did in Game 1, citing the tendency for things to even out.
In that case, Boston's penalty-killers must be prepared and focused for what may come. The Bruins should also be thinking about weathering a storm or two, since very few series ever move in a straight line. There are always twists and turns of momentum, and plot and strategy complications with every game.
The Bruins will not want to change their mindset, though, and that's to stay aggressive.
I see the Bruins as very consistent and battle-tested. They've been a top team all season long, unlike the Blues, who were last in the NHL on Jan. 3. Boston has experience and leadership in players like Patrice Bergeron, Zdeno Chara and Rask; that's a big plus, and it matters a lot at this time of the season.
They are the team ahead in the series, but the coaching staff has a big job ahead.
Even after a win, I think it's important for coach Bruce Cassidy and his staff to remain critical. I always preferred the sandwich method, which is to show positive clips at the start of video meetings, then sprinkle in some critical stuff -- things that you can improve upon -- then finish with more positive stuff. This leaves the players knowing it wasn't a complete or perfect game and focuses them on being hungry to do even better.
Boston's coaches and leaders have enough experience and depth to be able to keep everyone sharp and accountable. And at this stage of the playoffs, even with a win in Game 1, you know nobody will be overconfident.
The Bruins will be preparing for a tougher game ahead, enjoying the ride and knowing that this is likely to be a long series.
