Thanks in large part to Esposito's scoring exploits in 1970-71, Bobby Orr was able to register the best plus-minus rating in NHL history.
The dazzling defenseman put up career highs in assists (102) and points (139) en route to the record.
Orr's defensive partner Dallas Smith finished with a remarkable plus-94 rating that continues to rank fourth all time.
With individuals setting records left and right, the Bruins won a team-record 57 games.
Unfortunately for Orr and company, rookie Ken Dryden and the Montreal Canadiens shut down the Bruins in the playoffs, keeping them from winning the second title in a potential three-peat.
The Bruins currently employ a few elite plus-minus players, but that doesn't mean this record is within reach. Patrice Bergeron and Zdeno Chara have each led the NHL in plus-minus in the past three seasons, but neither player earned a rating better than plus-36.
Orr's plus-124 would require not only a player of his caliber but also a team capable of total domination at both ends of the ice. Don't expect this NHL record to ever be challenged.
