 The NFL had actually admitted the Bulldogs to the league for the 1937 NFL season, but reneged on the agreement because of travel concerns (the great distance between the Bulldogs and every other team, plus having to cross the Rocky Mountains in an era when travel by airplane was still a rare and hazardous endeavor, proved to be too much of a risk for the newly stable NFL to be willing to take; the league had finally stabilized in the mid-1930s after a decade and a half in which teams were leaving and joining the league annually).The NFL would hold its first two All-Star Games in Los Angeles following the 1938 and 1939 seasons.In 1946, the Los Angeles Dons of the All-America Football Conference started play, lasting four years before folding with the demise of the AAFC.
