A little bit of information about this league
The World Football League, or WFL, began in 1973 as the brainchild of Gary L. Davidson, the former president of the World Hockey Association (WHA) and one of the founders of the American Basketball Association (ABA). Planned as a Summer alternative to the NFL, the league debuted on July 10, 1974 with 12 teams in three divisions playing a 20 game schedule. The competition with the NFL was ripe from the beginning. With the labor agreement between the NFL and the players set to expire, as many as 60 NFL veterans signed future contracts with the WFL. Most notable were Larry Czonka, Paul Warfield and Jim Kiick of the championship Miami Dolphins, who agreed to play for the Memphis Southmen in 1975.
