One of the founders of the NFL, Halas bought the Decatur Staleys in 1921 and moved them to Chicago, where they became the Bears in 1922. "Papa Bear" won six NFL championships as a coach, and he also played receiver and defensive end. He signed former Illinois star Red Grange, lending legitimacy to the fledgling NFL, and he drafted Mike Ditka and later hired Ditka as head coach.
