Boston Bruins Thompson began his
National Hockey League (NHL) career with the
Boston Bruins in the
1928–29 season after his contract was purchased by Boston manager
Art Ross. Despite having never seen Thompson play, Ross had heard about Thompson's good reputation in Minnesota. In his first season, he appeared in all 44 of the Bruins' games, posting 12 shutouts and a 1.15 goals-against average, the fourth-lowest goals-against average in NHL history to date, behind
Alec Connell's 1.12 GAA and
George Hainsworth's 1.05 and 0.98 GAA. Hainsworth set his record that same season. Thompson recorded three shutouts in the five playoff games, and allowed only three goals. 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 goal-scoring. 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. In the
1930–31 season, he played all 44 games again, In the playoffs, Boston lost the semifinals to the
Montreal Canadiens; during game two of the series Thompson became the first goaltender to be pulled for a
sixth attacker at the end of a game to give his team a higher chance to score a goal. Even though Boston still lost, coach
Art Ross' maneuver was described as "amazing" the following day, and this technique, known as "open net", caught on with the rest of the league. The Bruins missed the playoffs for the first time in Thompson's career in the
1931–32 season. He won only 13 games while appearing in 43 out of Boston's 48 games, which was the only time he missed games as a member of the Bruins. as he recorded 11 shutouts and a 1.76 goals-against average. as Thompson was named to the second All-Star team for the second time. The ensuing two-game, total-goal playoff series against the Toronto Maple Leafs was a series of contrasts, as the Bruins lost 8–6. In the opening game, the Bruins shut out Toronto 3–0, while they lost the other game 8–3. Thompson set a new record by winning his fourth and final Vezina Trophy. He was also named to the first All-Star team for the second time. To make space for Brimsek, Thompson was traded to the
Detroit Red Wings for
Normie Smith and $15,000 on November 16, 1938; Thompson also received a $1,000 bonus from Boston. Boston manager Art Ross predicted that Thompson, now 35, would play for the Red Wings for at least another five seasons; however, Thompson remained with the team for only two seasons before retiring from playing. The Red Wings posted a losing record in both of these seasons, although they made the playoffs both times. Overall, Thompson appeared in 85 regular-season games for Detroit, recording a 32–41–12 record, seven shutouts, and a 2.54 goals-against average, and in 11 playoff games, posting a 5–6, with one shutout and a 2.41 goal-against average. ==Post-NHL career==
