Marchand has 20 points (12 goals, eight assists) over his last 11 games and 48 points (27 goals, 21 assists) over his last 31 contests. He ranks second in the NHL in goals (37), just behind his former World Cup of Hockey linemate and fellow Nova Scotia native Sidney Crosby (40). Marchand's 79 points also place him second behind Crosby and Connor McDavid (80).
"He's a leader of our hockey team that he knows the urgency of where we are in the season, game in and game out, and he wants to extend the season, there's no doubt about it, and it shows every night," said Cassidy, whose team sat three points ahead of Toronto for third place in the Atlantic Division ahead of the teams' Monday night showdown.
"He's pulled some guys along…he's one of the heart and soul guys of this team, and at both ends of the ice."
This was made clear during Marchand's stellar third period against the Canucks. Down by a goal entering the third period, Marchand put the Bruins on his back, potting three goals in the final frame - including the tying and winning tallies - to lift Boston to a 6-3 victory.
"When we need somebody to pick us up, he's often the guy who kind of takes over the game and scores a big point or makes a big play, and [the Vancouver game] was a great example, obviously," said Tuukka Rask, who has had a front-row seat to Marchand's entire eight-year Bruins career.
Many have pointed to Marchand's success at the 2016 World Cup of Hockey as the starting point for his assent to being one of the NHL's elite. The winger joined Crosby and Bergeron to form one of the most potent lines in the tournament, during which he notched had eight points (five goals, three assists), once again second to Crosby (10 points).
"I think he just keeps improving from one year to another," said Bergeron. "This year he took an even further step forward. From the World Cup on he took off. He's definitely an elite player and super star in this league. I think he's proving that right now. He's been a lot of fun to watch, but also a lot of fun to play with."
