For the first time since Dec. 10, the Bruins tasted defeat on Saturday, snapping a remarkable 10-game run of success. And for the first time since Oct. 23, they lost at home, a 14-game string of victory. How long ago was that? The Red Sox  had just lost Game 7 of the ALCS to Tampa Bay four days earlier. Afterward, every Bruin to a man talked about facing adversity and how they plan to learn from this loss. Perhaps Milan Lucic  said it best when he said that “good teams don’t lose two in a row and we have to be hungry come our next game.” That will be the focus when they continue their six-game homestand against Minnesota on Tuesday night. But for now, we look back on a game with the help of coach Claude Julien , who introduced a new term into the lexicon of the Boston sports fan. “We needed some JAM and this was one of those games where you need a little bit more JAM.” JAM is apparently hockey-talk for juice, energy and desire.
