After resigning from the Packers, Coach Curly Lambeau filled the open head coach position of the Chicago Cardinals. In addition to the position of head coach, Lambeau also was named vice president and was given complete control of personnel choices. The 1950 season was Lambeau’s first in Chicago. The team ended the season 5–7, failing to improve upon its record in the previous season and missing out on the postseason. The 1951 season went even worse for Lambeau and the Cardinals; the team ended the season 3–9 and again failed to reach the postseason
Announcement of Lambeau’s resignation came during an attempted reorganization of the club in which Lambeau had waged a fight for control against a faction which sought to oust him. In a letter Wednesday to Emil R. Fischer, president of the Packer corporation, who is now on vacation in Florida, Lambeau blamed the club’s internal strife for his resignation.
