For all the progress the Bruins made in 2010-11, there was still one bit of business they had to put behind them from the year before.

After blowing a 3-0 series lead against the Philadelphia Flyers in the Eastern Conference Semifinals, the two teams met again a year later with a spot in the Eastern Conference Finals on the line. The outcome in the first three games was exactly the same from the year before with the Black and Gold taking a three games to none lead entering Game 4 at TD Garden on this day five years ago.

Unlike the year before where injuries to Marco Sturm and David Krejci hampered the Bruins in the long run — and a returning Simon Gagne sparked the Flyers’ historic comeback — the two teams were trending in opposite directions. The Bruins were all healthy for the most part while the Flyers were without star defenseman Chris Pronger due to ongoing concussion issues.

Nonetheless, it was a chance for the Bruins to close a haunted chapter in their history book. They did just that.

Two goals from Milan Lucic and a third period outburst led by Johnny Boychuk’s go-ahead blast gave the Bruins a 5-1 victory and completed the series sweep of the Flyers.

The win did come at a cost, however, as Patrice Bergeron suffered a mild concussion and would miss the first two games of the Eastern Conference Finals against the Lightning. That would prompt a phenom by the name of Tyler Seguin into the lineup. And of course, we’ll touch on that in the coming days.

For now, let’s relive the Bruins putting history behind them with some highlights.
