The following season, Thompson again appeared in all of the Bruins' 44 games, posting three shutouts and a 2.19 goals-against average. The league changed its rules on forward passing, which resulted in a sharp increase in goalscoring. Boston won all but six games, finishing with a 38–5–1 record, the best winning percentage for any team in a season. Surrendering only 98 goals, Thompson bested Chicago goaltender Charlie Gardiner to win the first of his four Vezina Trophies. The Vezina Trophy is awarded to the league's top goaltender, which was determined prior to the 1981–82 season by number of goals surrendered by goaltenders who had played a minimum number of games. In the playoffs, however, they suffered their first two-game losing streak, as they were swept 2–0 by the Canadiens in the Stanley Cup finals. Earlier in the playoffs, Thompson's winning streak of seven playoff games was snapped; it remains, as of 2014, the longest playoff winning streak to start a career.
