Prior to the season, the league decided to eliminate the financially weaker teams. As a result, the league dropped from 22 to 12 teams, and a majority of the remaining teams were centered on the East Coast instead of the Midwest, where the NFL had started. The league absorbed many players and one franchise from the defunct American Football League. Although five black players participated in the 1926 season (including future Hall of Famer Fritz Pollard), none played during the 1927 season. The New York Yankees were added from the American Football League (albeit technically as a continuation of the defunct Brooklyn franchise), Cleveland Bulldogs returned and Buffalo Rangers returned to the Buffalo Bisons name. The Bisons would suspend operations five games into the season (all losses). The teams that would be dropped from the league were Kansas City Cowboys, Los Angeles Buccaneers, Detroit Panthers, Hartford Blues, Brooklyn Lions, Canton Bulldogs, Milwaukee Badgers, Akron Indians, Racine Tornadoes, Columbus Tigers, Hammond Pros, and Louisville Colonels. The elimination of the majority of the Ohio teams left the Dayton Triangles as the last surviving connection to the Ohio League, which served as the basis for the NFL's founding. After seven weeks, the Chicago Bears were unbeaten at 5–0–1, followed by the once-beaten New York Giants (6–1–1) and Green Bay Packers (5–1–1). Two games played in New York City on Tuesday, November 8, changed the standings. The New York Yankees handed the Bears a 26–6 defeat, while the Giants beat Providence, 25–0. At 7–1–1, the Giants were in first place,
while the Bears and Packers were tied for second (5–1–1). On November 20, the Bears beat the visiting Packers, 14–6, and, at 7–1–1, were within striking distance of the 8–1–1 Giants. Thanksgiving Day, however, saw the Bears lose at Wrigley Field to their crosstown rivals, the Chicago Cardinals. With three games left, the most important game of the regular season took place on November 27, at the Polo Grounds where 15,000 turned out to watch the Bears (7–2–1) face the Giants (8–1–1). A Bears' win would have tied the teams for first place, but the Giants won, 13–7. The New York Giants and New York Yankees closed their seasons with a two game series. At home at the Polo Grounds, the Giants beat the Yankees 14–0 to clinch the title on December 4, and then beat them again at the old Yankee Stadium on December 11, to finish at 11–1–1, and lay claim to the NFL Championship.
