On every Bruins broadcast, commentators talk about toughness. They point to the club's bruisers -- Milan Lucic, Shawn Thornton and others -- as the differentiating factor and the embodiment of this team. There's certainly some value to these players, especially Lucic, and the influence they have on games is unquestioned.

Toughness, though, takes many forms. Hockey coaches are fond of discussing mental toughness. The ability to be the same player in 6-0 blowout and a one-goal game. Throughout the league, there are several players that define this, but no one on Causeway Street is a greater manifestation of this concept than Patrice Bergeron. He isn't a fighter. He isn't a power forward or a bottom-six grinder that hockey oldest souls glorify despite questionable value. In every sense of the word, Patrice Bergeron is hockey player -- a pretty damn tough one at that.

Thursday night, the Bruins dispatched the Toronto Maple Leafs for what seems like the 100th time in a row. The usual combination of smart defense, solid goaltending and timely offense led to the win. And, just as typically, it was Bergeron at the center of it all.
