It was the unlikeliest of Game 7 comebacks for a hockey club that has blown nine third-period leads this season, and has regularly been tormented in the last 20 minutes of games all year.

But it was also true to their “Dr. Jekyll and Mr. Hyde” nature that the Boston Bruins -- trailing 4-1 and facing elimination (and more) -- potted three goals in the final 10 minutes and 42 seconds of a Game 7 elimination game, two of them within 31 seconds of each other after Tuukka Rask had pulled for a sixth skater, to tie the game, and went on to a thrilling, epic 5-4 overtime win over the Toronto Maple Leafs Monday night at TD Garden.

“That was unbelievable” said defenseman Johnny Boychuk. “That’s one thing you’re going to remember probably for the rest of your life, because it was such a comeback that everybody probably thought that we were done. It showed what kind of character there is in this dressing. Never say die.”

It was yet another example of the "bipolar hockey experience" that is the 2012-13 Bruins. Their opponents have no idea what to expect, which makes the Black and Gold an unpredictable and highly dangerous opponent. But the B's also have no idea what to expect out of themselves, except that they seemingly need an axe hanging over their heads in order to thrive.
