Pro football in California with a major league did not occur until 1946 when the Cleveland Rams moved to Los Angeles, and the San Francisco 49ers and Los Angeles Dons became charter members of the All-America Football Conference (AAFC). But prior to the invention of the AAFC, there was a pro football league called the Pacific Coast Professional Football League (PCPFL) which operated from 1940-1948.

The PCPFL was considered a high brow version of semi-pro football, and in fact, from 1942-1945 it’s only rival talent-wise was the NFL. Many a player in the PCPFL found future employment in the NFL as well as the AAFC in later years. At the time, most west coast cities, although with large populations, were problematic as far as travel since the most widely used transportation utilized in those days was by railroad. Nobody wanted to spend more than a day by rail to travel to or from another NFL city, so the western United States was merely unattainable until advancements in travel prevailed.
