In 1981–82, the NHL realigned its conferences and adopted an intra-divisional playoff format for the first two rounds. It was the beginning of an era in which the Sabres would finish in the middle of the Adams Division standings with regularity, and then face the near-certainty of having to get past either the Boston Bruins or Canadiens to make it to the conference finals. Aside from first-round victories over Montreal in 1982–83 and Boston in 1992–93, the era saw the Sabres lose to division rivals Boston, the Quebec Nordiques and Montreal in the Adams Division semi-finals (first round) a combined eight times, and miss the playoffs altogether in 1985–86 and 1986–87—only third and fourth times out of the playoffs in franchise history. Perrault reached the 500-goal mark in the 1985–86 season and retired after playing 20 games in 1986–87, 17 years after joining the Sabres as their first draft pick.
