For the record, the Chiefs aren't named after American Indians...they are named after H. Roe Bartle, former KC mayor who was known as "Chief."
Harold Roe Bennett Sturdyvant Bartle (June 25, 1901 – May 9, 1974), better known as H. Roe Bartle, was an American businessman, philanthropist, executive, and professional public speaker who served two terms as mayor of Kansas City, Missouri.
After Bartle helped lure the Dallas Texans American Football League team to Kansas City in 1962, owner Lamar Hunt renamed the franchise the Kansas City Chiefs after Bartle's nickname, The Chief.
