サンフランシスコ・フォーティナイナーズの初代監督はだれ？
There have been 19 head coaches in the history of the San Francisco 49ers professional football franchise. The San Francisco 49ers franchise was formed in 1946 as a charter member of the All-America Football Conference (AAFC) before joining the National Football League (NFL) in 1950 after the AAFC merger with the NFL. Buck Shaw became the first head coach of the 49ers in 1946, serving for nine seasons—four in the AAFC and five in the NFL. He coached a number of future College and Pro Football Hall of Famers, such as Frankie Albert, Joe Perry, Leo Nomellini, Y. A. Tittle, Bob St. Clair and Hugh McElhenny.
