It was during his rookie season of 1974–75, in the playoffs, that Gillies established himself as one of the toughest players in the National Hockey League (NHL). enforcer Dave Schultz. In the latter half of the 1976–77 season, Gillies was named team captain; however, in spite of Gillies' articulate speaking manner and amiable nature, he never felt completely comfortable as captain. Gillies captained the Islanders through two disappointing seasons, in part because the Islanders appeared to lack team toughness. During the pre-season of 1979–80 Gillies allowed Denis Potvin to take over as captain. During the 1980 playoffs, Gillies got the best of Terry O'Reilly, one of the Boston Bruins' toughest players, several times, helping to fuel the Islanders' drive to the Stanley Cup.

After scoring only four goals in 55 games in 1985–86, Gillies was left unprotected in the NHL waiver draft, and was claimed by the Buffalo Sabres. While wearing number 39 in Buffalo, Gillies retired after playing a season and a half with the Sabres. On December 7, 1996, Gillies' No. 9 was retired by the Islanders.
