The All-America Football Conference and the National Football League battled for supremacy from 1946 through 1949. In the end, the players from the AAFC, as well as three teams, were brought into the NFL. Through extensive research, the Professional Football Researchers Association (PFRA) has corrected the statistics and coaching records, selected offensive and defensive All-Pro Teams for all four seasons and an All-Conference team, and provided brief biographies and scouting reports for the members of the All-Conference Team.
