1944–45 NHL season

The 1944–45 NHL season was the 28th season of the National Hockey League. Six teams each played 50 games. The Toronto Maple Leafs won the Stanley Cup in seven games versus the Detroit Red Wings.

League business
In October 1944, Lester Patrick sponsored W. G. Hardy to become NHL president, replacing Red Dutton who wanted to step down. Patrick credited Hardy for being largely responsible for the current professional-amateur agreement between the NHL and the amateur associations in the International Ice Hockey Association, and said he was "temperamentally suited and has an excellent record as an executive of the Canadian Amateur Hockey Association".

Regular season
It was the year of the "Punch Line" as Rocket Richard scored 50 goals in 50 games, breaking Joe Malone's record of 44 goals, and when Richard scored his 45th, Malone was on hand to present him with the record-breaking puck. Richard had a five-goal, three-assist night against Detroit at the Montreal Forum on December 28, 1944. His centreman, Elmer Lach, though, won the scoring race with 26 goals and 80 points. Toe Blake finished third with 29 goals, 38 assists, and for the second time, an entire line finished first, second, third scoring. The previous time had been in 1939–40, when the Boston Bruins' Kraut Line of Milt Schmidt, Bobby Bauer and Woody Dumart accomplished the feat. Schmidt finished with 52 points in 48 games that year, and Bauer and Dumart 43 apiece.

Montreal dared not loan Paul Bibeault to Toronto again with his fine year the previous season and loaned him instead to Boston. But the Maple Leafs came up with a fine rookie named Frank McCool who won the Calder Memorial Trophy as the league's top rookie. For the first time, a team produced three consecutive top rookies. McCool and Chicago netminder Mike Karakas tied for the league lead in shutouts with four each.

Bill Durnan won his second consecutive Vezina Trophy with Montreal. Flash Hollett became the first defenceman to score twenty goals in one season. The record would stand until Bobby Orr broke it several decades later.

A major trade that occurred this year was Chicago trading their great defenceman Earl Seibert to Detroit for Don Grosso, Cully Simon and Byron "Butch" McDonald. After team owner Frederic McLaughlin died, it was just a matter of time before Bill Tobin would trade Seibert, as the two did not get along.
