1926–27 NHL season

The 1926–27 NHL season was the tenth season of the National Hockey League. The success of the Boston Bruins and the Pittsburgh Pirates led the NHL to expand further within the United States. The league added three new teams: the Chicago Black Hawks, Detroit Cougars, and New York Rangers, to make a total of ten, split in two divisions. This resulted in teams based in Canada being in the minority for the first time. To stock the teams with players the new teams brought in players from the Western Hockey League, which folded in May 1926. This left the NHL in sole possession of hockey's top players, as well as sole control of hockey's top trophy, the Stanley Cup, which was won by the Ottawa Senators. This was the original Senators' eleventh and final Stanley Cup win. The Senators' first was in 1903.

League business
NHL expansion was the main topic of discussion between the NHL owners at the April 1926 and May 1, 1926 league meetings. The new New York Rangers franchise was approved in principle after the Madison Square Gardens president Hammond agreed to revenue sharing. President Calder, plus owners Strachan and Dandurand formed a committee to study franchise candidates in Chicago, Detroit, Jersey City and Philadelphia, while further applications from Cleveland, New York, Chicago, Philadelphia and Detroit were received. The owners were split on which new franchises to accept. Part of the disagreement was over the Chicago franchise. Sports promoter Paddy Harmon had announced a new Chicago Stadium and backed a team in partnership with Thomas Duggan, while Madison Square Garden's Tex Rickard wanted to build a Chicago Madison Square Garden with the participation of Huntington Hardwick.

At the 1926 Stanley Cup Finals, WHL president Frank Patrick had begun shopping the WHL's players to the NHL, hoping to raise $300,000 to distribute to the WHL owners. Patrick approached Art Ross of the Bruins, who agreed to purchase the contracts of Frank Fredrickson, Eddie Shore, and Duke Keats. After the series, Patrick approached the new New York Rangers owner Charles Hammond and their general manager Conn Smythe, but they were turned down. Patrick and Ross approached the Bruins' owner who agreed to purchase the entire lot of players for $250,000, and gave Patrick a $50,000 check as a deposit. He planned to keep some of the players for the Bruins, sell twelve players each to the new Chicago and Detroit franchises and distribute the rest to the rest of the league.

At a May 14 meeting, the NHL awarded the Detroit franchise to the syndicate of Wesson Seybourn and John Townsend, formed by Charles A. Hughes. The split over the new Chicago franchise prevented its immediate acceptance as a new franchise required unanimity. However, the NHL governors could amend their constitution with a two-thirds vote, and they amended the constitution at the May 14 meeting to lower the bar for a new franchise to a simple majority vote. The governors agreed that Huntwick would get the Chicago franchise. Huntwick proceeded to buy the Portland Rosebuds and the Hughes group purchased the Victoria Cougars, each for $100,000. The Bruins took Fredrickson, Shore, Keats and others, while the Rangers took Frank Boucher. In total, the player's contracts purchased that day totalled $267,000 for Patrick to take back to the WHL. On May 15, the NHL awarded the franchises to the Hardwick and Hughes consortiums, with provisos that each team would have an NHL-ready team for September 1, and new arenas by November 10.

At the September 25, 1926, NHL meeting, the Chicago Black Hawks, Detroit Cougars and New York Rangers were added to the league. The Hughes consortium proceeded with the purchase of the Cougars and the franchise, while the Chicago franchise instead went to Frederic McLaughlin, who took over the deal from Huntwick on June 1. The NHL's second franchise in New York City went to the Madison Square Garden syndicate of John S. Hammond. Both Detroit and Chicago had not begun construction on arenas. Detroit would play in Windsor, Ontario at the Border Cities Arena, while the Black Hawks played at the Chicago Coliseum.

Toronto bought the players of the Saskatoon franchise separately, and Montreal claimed George Hainsworth. The rest of the WHL players would be distributed by a committee of Frank Calder, Leo Dandurand and James Strachan. The former WHL players make an impact in the NHL. The top scorer was Bill Cook, the top goalie was George Hainsworth, and defenceman Herb Gardiner was the league MVP.

A special meeting was held on October 26 at which the NHL was split into the Canadian and American divisions. It was the first divisional format to be implemented in a major professional North American sports league. To balance the divisions, the New York Americans were placed in the Canadian Division. With the new divisional alignment came an altered playoff format: the top team from each division would meet the winner of a total-goals series between the second and third place teams from their divisions. The winners of those total-goals series would meet in a best-of-five Stanley Cup Finals.

The Central Hockey League changed its name to the American Hockey Association. The new AHA signed an agreement of co-operation with the NHL, wanting to place itself on an equal footing with the NHL, but non-competitive. However, the new AHA placed franchises in Chicago and Detroit, competing with NHL teams. The Chicago Cardinals were backed by old nemesis Eddie Livingstone and became a source of friction with the NHL. Calder declared that several of the Cardinals' players were illegally signed and broke off the agreement with the AHA. The AHA could not compete with the NHL and the Detroit franchise folded in December, and the Chicago franchise folded in March. The AHA then signed another cooperation agreement with the NHL and forced Livingstone out.

Majority ownership of the Toronto St. Patricks was sold on February 14, 1927 to a syndicate headed by Conn Smythe for CA$160,000. Nathan Nathanson sold his interest entirely, while J. P. Bickell retained his share of the company. The club was officially renamed the Toronto Maple Leafs and Bickell became its president, but the league ruled that the team must remain using the St. Patricks name until season's end.

Rules changes
The blue lines moved to sixty feet from the goal line from twenty feet from the center red line to increase the size of the neutral zone.

Two innovations attributed to Art Ross are adopted by the NHL. The league adopts a modified puck, which has rounded edges. The net is modified to keep the puck in the webbing.

Regular season
The Montreal Canadiens, last place finishers in 1925–26, solved their goaltending woes by signing George Hainsworth. They further strengthened their team by signing Herb Gardiner of the Western League's Calgary Tigers for defence. The Canadiens finished second in the Canadian Division to powerful Ottawa, who was the league's best team.

Dave Gill, secretary-treasurer (general manager), decided to take over as coach of the Ottawa Senators. He would be assisted by Frank Shaughnessy, a former manager of the Senators in the NHA days, to assist him with the strategy used in games. Ottawa finished first atop the Canadian Division.

The arena is not ready in Detroit for the start of the regular season. The expansion Cougars play their first 22 home games just across the Canada–United States border in Windsor, Ontario, at the Border Cities Arena.

On December 4th, 1926, Cy Denneny and Frank Finnigan were seriously injured in a car accident. Finnigan suffered a slightly fractured skull and Denneny was badly gashed.

New York Americans right winger Shorty Green's career was ended after an injury in a game on February 27, 1927. New York Rangers defenceman Taffy Abel bodychecked Green, caused a kidney injury that requires an emergency operation to remove the kidney; Abel retired for health reasons.

Playoffs
With the collapse of the Western Hockey League, the Stanley Cup became the championship trophy of the NHL. The NHL teams now battled out amongst themselves for the coveted Cup. The new division alignment and the new playoff format also meant that an American team was guaranteed to be the first American NHL team to make the Cup Finals.

The division winners received a bye to the second round. The second-place and third-place finishers played a two-game, total-goals series to advance to the second round. The second-place Montreal Canadiens and Boston Bruins both advanced to the second round. The Canadiens lost to the first-place Ottawa Senators, while the Bruins upset the first-place New York Rangers to set up the Finals. Ties were not broken using overtime. After two ties in the Finals, Ottawa won two to Boston's none and the series ended on April 13 with Ottawa the winner.

Game one of this series was played in New York.

Awards
A new trophy in memory of Georges Vezina, the Vezina Trophy, was donated this year by Montreal Canadiens owners Leo Dandurand, Louis Letourneau and Joseph Cattarinich. It is to be presented to the league's "most valuable goaltender." It is won by his successor with the Canadiens, George Hainsworth.
