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 transition from A.E. Staley's leadership to George Halas' took place at the beginning of the season, resulting in an improved record for the team from 10–1–2 in 1920 to 9–1–1 under Halas' guidance, securing their first-place finish and league championship (the most successful season of the 1st Halas era). The team was then relocated to Chicago.
