Offense came to the fore in the NHL during the 1970s.
In a decade that saw the League add two teams each in 1970, 1972 and 1974, scoring took center stage. Average goals per game went from slightly less than six at the start of the decade to seven by 1979. Seasons in which top players reached 50 goals and/or 100 points no longer were uncommon.
It was a decade that saw Phil Esposito of the Boston Bruins shatter the single-season marks for goals and points by scoring 76 times and finishing with 152 points in 1970-71. Four years later Esposito's teammate, Bobby Orr, led the NHL in scoring for the second time with 135 points.
Orr perhaps is the most revolutionary player ever in the NHL. Before his arrival defensemen weren't expected to be major offensive contributors. But by the 1970s every team felt it had to have at least one puck-rushing defenseman in order to keep up with the way the game was being played.
"What Bobby did was make coaches think we don't have to stick a guy who can't skate back there and instead say, 'Let's put a guy who can skate and get him on the ice more,'" Hockey Hall of Fame defenseman Brian Leetch told NHL.com in 2013.
With so much offense on display, a 3-on-3 All-Star format at some point during the 1970s would have been a sight to see. Here is NHL.com's attempt at establishing an All-Time 3-on-3 Team of the 1970s.
