The Bruins introduced new white jerseys with a brown block "B" and secondary colours of brown and gold trim. The socks became predominately white.
After missing the playoffs the previous season, largely due to line-up instability, the Bruins returned to form in the 1932-33 season. The acquisition of established scorer Nels "Old Poison" Stewart from the Montreal Maroons more than made up for the loss of Cooney Weiland with Stewart finishing second in scoring on the team and 9th in the league. Marty Barry continued to shine, leading the team in scoring and 7th in the league. Eddie Shore had the most productive season of his career and won his first Hart Memorial Trophy as MVP while Tiny Thompson led the league in goals against average, shutouts and won his second Vezina Trophy.
The league's two best teams met in the second round of the playoffs, both teams having received byes in the first round. The series was one of the closest in NHL history with four of the five games being decided in overtime.
Game 1 after Dit Clapper tied the game at 1-1 in the second period, overtime was needed to decide the game. The Bruins leading scorer Marty Barry potted the winner at 14:14 of the first OT period.
Game 2 was a close checking affair with the only goal scored by Busher Jackson at 15:03 of the first OT period to tie the series at 1-1. Lorne Chabot registered the shutout.
Game 3 saw the Bruins lead on a goal by Nels Stewart at 4:47 of the second period until Ken Doraty tied it up with less than six minutes left in the game. To no avail as Eddie Shore scored at 4:23 of the first OT period.
Game 4 was the only wide-open affair of the series. A pair of goals by Busher Jackson and Charlie Sands (who would later play for the Bruins and become one of their top ten scorers of the 1930's) led the Leafs to a 5-3 victory and tied the series 2-2.
Game 5 was the second longest game in NHL history requiring six overtime periods before Ken Doraty scored at 4:46 on Tiny Thompson to win the series for the Leafs. Lorne Chabot picked up his second shutout of the playoffs. The Leafs would lose to the Rangers in the finals.
