A bonus choice was made for the first time in the NFL draft. One team each year would select the special choice before the first round began. The Chicago Bears won a lottery and the rights to the first choice and drafted back Bob Fenimore of Oklahoma A&M. The Cleveland Browns again won the AAFC title, defeating the New York Yankees 14-3.
Charles Bidwill, Sr., owner of the Cardinals, died April 19, but his wife and sons retained ownership of the team. On December 28, the Cardinals won the NFL Championship Game 28-21 over the Philadelphia Eagles, who had beaten Pittsburgh 21-0 in a playoff.
