From that point on, it was all Leafs, as they managed to score four goals against Tuukka Rask and took a commanding 4-1 lead into the final 10 minutes of the game.
That's when all hell broke loose. The Leafs, who were a hard forechecking, shot-taking machine in the first two periods, elected for a sit-back-and-wait approach, often electing to play a 1-4 neutral-zone trap.
What the Bruins did was simple. They dumped and chased against a very young and inexperienced Leafs defence. The Bruins seemed to come in waves, and the pressure was too much. Patrice Bergeron would tie the game as Zdeno Chara picked himself up out of the crease just as the puck passed by James Reimer.
After a wonderful stop by Rask on Joffrey Lupul not once, but twice, the Bruins gained all the momentum they needed.
The Bruins would continue their onslaught as they peppered Reimer with shots from all angles. One shot by Tyler Seguin ricocheted off of Reimer and onto Jake Gardiner's stick, but he handed it to Bergeron for the game-winning goal in overtime.
The Leafs can hold their heads somewhat high, as they took their regular-season nemesis, the Boston Bruins, right to the brink. They showed everyone they can beat them but still haven't proven they can beat them in the playoffs, sadly.
Here's a look back at my five keys to victory, which obviously didn't happen in this playoff series.
