That dedication and desire is what made that era of Bruins hockey so beloved by a city that has long embraced such qualities in its athletes and teams. The organization - and the fanbase - demands that kind of team-first culture and hard-working attitude, both of which continue to be hallmarks under the current leadership group, which has been headed for over a decade by Zdeno Chara and Patrice Bergeron.
"I used to live in fear that the personality of that 1970 [team] and the attitude of the 1970 team and style of the 1970 team would go away once we lost some of the players, but that didn't happen," said Sinden, now a senior advisor to Bruins ownership, who began working for the club in 1960.
"It carried over and we had many teams that played with the same spirit and the same idea as that team…what [that 1970] team and the players established as an example for the way you have to behave and the way you have to play in Boston has never gone away.
"The fans won't let it go away. You guys [in the media] certainly won't let it go away. As long as we can keep that alive, we're gonna be challenging for the Stanley Cup forever."
Sinden's first Stanley Cup dreams began to materialize in 1966 when he took over as the Bruins' head coach at the same time that 18-year-old kid from Parry Sound debuted on the Boston blue line.
"When I saw Bobby Orr on the ice for the first time," Sinden recalled, "I said, 'We're on our way.'"
That the Bruins were. But it took some time.
Boston missed the playoffs for the eighth consecutive season in 1966-67, but in Sinden's second campaign behind the bench the Bruins returned to the postseason with a boost from a legendary trade with Chicago that landed the Black & Gold Phil Esposito, Ken Hodge, and Fred Stanfield.
With Sanderson - he won the Calder Trophy as rookie of the year with 24 goals and 49 points - on board and Cheevers now manning the pipes, the Bruins were beginning to set the tone for a run of sustained success.
"When that [trade] happened…that gave us two solid lines," said Sinden. "And Sanderson broke into the league as one of the great rookies to ever break into this league, believe me. And Cheevers came back from the minors. Now we had a team.
"I think it was time for some identity to be established and a personality to be established. Those players did that."
They certainly did, as just two years later they posted a 40-17-19 record en route to the organization's first Stanley Cup since 1941.
