The NFL decreased to 10 teams, and halfway through the season the Frankford franchise folded. Carr fined the Bears, Packers, and Portsmouth $1,000 each for using players whose college classes had not graduated. The Packers won an unprecedented third consecutive title, beating out the Spartans, who were led by rookie backs Earl (Dutch) Clark and Glenn Presnell.
