Take advantage of Chicago using their timeout already.. pour on as much pressure as you can and make them have to ice it.
The good thing about being down 1 going into the third (if there is such a thing as that being good, lol) is that Chicago may be more prone to trying to preserve that lead for a period rather than build on it.. And Boston is forced to try and tie it up.
The ball is in the Bruin's court as far as setting the tempo for the 3rd goes.
