1921 Chicago Staleys season

The 1921 Chicago Staleys season was their second regular season completed in the young American Professional Football Association. The team improved on their 10–1–2 record from 1920 to a 9–1–1 record under head coach/player George Halas earning them a first-place finish in the team standings and their first league championship (the best finish of the 1st Halas era). The beginning of the season saw A.E. Staley turn over the team to Halas and Dutch Sternaman, who moved the team to Chicago. The team name was changed from the Decatur Staleys to the Chicago Staleys due to a contract between Staley and Halas. The Staleys were quite dominant, but all of Chicago's games were played at home (including one game in Decatur). Two games were against the Buffalo All-Americans; the first, played on Thanksgiving, was won by Buffalo 7–6, giving the Staleys their only loss of the season.

Ed "Dutch" Sternaman and George Halas starred again, with newcomer Gaylord Stinchcomb also contributing. Sternaman scored 32 points, most by kicking, and threw one touchdown pass. Halas had 3 TD receptions while Stinchcomb led the team with 4 touchdown runs.
