1941–42 NHL season

The 1941–42 NHL season was the 25th season of the National Hockey League. Seven teams played 48 games each. The New York Americans rebranded as the Brooklyn Americans. The Toronto Maple Leafs won the Stanley Cup defeating the Detroit Red Wings winning four straight after losing the first three in a best-of-seven series, a feat only repeated to date three times in NHL history (1975, 2010, 2014) and once in Major League Baseball (2004). However the '41–42 Leafs were the only ones to achieve the feat in a championship final series.

League business
This was the last season for the Brooklyn Americans who had changed their name from the New York Americans in an attempt to build a civic relationship with those from the Flatbush area of New York. However, the team continued to play at Madison Square Garden in Manhattan since there was no suitable arena in Brooklyn.

Due to World War II travel restrictions on adults, the NHL demanded more junior-aged players who were free of the travel restrictions. NHL president Frank Calder reported there was a general agreement with the amateur leagues that a junior-aged player should be able to determine his own financial future due to the war.

Regular season
The Americans started the season without Harvey "Busher" Jackson who refused to sign. He was then sold to Boston. But the Amerks had two positive notes: two defencemen, Tommy Anderson and Pat Egan, were now All-Star calibre. That did not prevent them from finishing last, though. On December 9, 1941, the Chicago Black Hawks-Boston Bruins game would be delayed for over a half-hour as United States President Franklin Delano Roosevelt declared that the United States was at war.

Frank Patrick suffered a heart attack and had to sell his interest in the Montreal Canadiens, and the Habs almost had to move to Cleveland. But Tommy Gorman kept the team alive. They added Emile "Butch" Bouchard to start his great career on defence and another very good player, Buddy O'Connor, at centre. Montreal had goaltending problems as Bert Gardiner slumped, and rookie Paul Bibeault replaced him. He showed flashes of brilliance, but his inexperience showed. Joe Benoit starred with 20 goals, the first Canadien to do that since 1938–39, when Toe Blake did it.

The New York Rangers had a new goaltender as Sugar Jim Henry replaced the retired Dave Kerr. Henry was one of the reasons the Rangers finished first, something they did not do again for the next 50 years.
