McNab - affectionately known as "Maxy," after his father, Max, a longtime player, coach, and GM in the NHL - twice scored playoff overtime winning goals for the Bruins, the first coming on April 21, 1978, in Game 3 of the first round against Chicago and the second on April 23, 1982 in Game 6 of the second round against Quebec.
McNab, who played 595 regular-season games for Boston, ranks 11th in Bruins history in goals (263), 13th in points (575), and 16th in assists (324). On Boston's all-time postseason lists, he ranks eighth in goals (38), 13th in points (74), and 18th in assists (36).
"I love this fact, that Bobby Orr and I will never be separated," McNab recalled in that 2018 interview. "Bobby's got 264 [goals], I've got 263, so no one can ever come between me and Bobby Orr. We're cemented in Bruins history. I'll be right by him…that is unbelievable."
McNab is also one of six Bruins with six-or-more 30-goal seasons, along with Phil Esposito, Rick Middleton, Johnny Bucyk, Cam Neely, and Patrice Bergeron.
The 6-foot-3, 205-pounder was traded to the Vancouver Canucks in 1984 and spent two seasons there before finishing his career with two seasons for the New Jersey Devils. Overall, McNab played 954 games with 363 goals, 450 assists, and 813 points. In 107 career playoff games, McNab tallied 40 goals and 42 assists for 82 points.
McNab went on to have a highly successful career as a broadcaster beginning with the Devils in 1987-88. He joined the Avalanche broadcast team for their inaugural season in 1995-96 and was the club's color analyst for each of their 26 seasons in the NHL.
In 2021, McNab was inducted into the U.S. Hockey Hall of Fame.
