also one of two Hall of Famers (the other being Sid Luckman) to play in the American Association. Fifteen inductees spent some of their playing career in the All-America Football Conference during the late 1940s. Five players played some at least one year in the Ohio League, the predecessor to the NFL. Six players or coaches who spent part of their careers in the short-lived United States Football League (USFL) have been inducted. Two coaches (Marv Levy, Bud Grant), one administrator (Jim Finks), and five players (Warren Moon, Fred Biletnikoff, John Henry Johnson, Don Maynard, Arnie Weinmeister) who spent part of their careers in the Canadian Football League (CFL) have been inducted; three of which have been or are scheduled to be inducted into the Canadian Football Hall of Fame: Marv Levy, Warren Moon and Bud Grant. Four players, Larry Csonka, Leroy Kelly, Don Maynard, and Paul Warfield, played a portion of their career in the short-lived World Football League. Fritz Pollard is the only player to play in the Anthracite League's only season. One player (Kurt Warner) and one owner (Pat Bowlen) made significant contributions in the Arena Football League; Warner and Art McNally are also the only NFL Europe/World League alumni in the Hall. Terrell Owens played one season of professional football in the Indoor Football League and, after his induction, is playing in Fan Controlled Football. Bill Walsh and Ken Stabler each had one season of experience in the Continental Football League. Each entry includes the year of induction (i.e., "class"), position(s) played, team(s) each was associated with, and tenures with each team. As some inductees were both players and coaches, the position indicated here is the position indicated on the Hall of Fame website. The Pro Football Hall of Fame website does not include CFL, USFL, WFL, indoor football leagues, and other lesser known league teams. The Canadian Football League and the Arena Football League both have their own halls of fame. NFL, American Football League, All-America Football Conference, and Ohio League (listed as pre-NFL) teams are recognized in the Hall of Fame. The list is complete through the Class of 2022.
