Funny thing about the Chiefs — they were named for the Mayor at the tine, H. Roe Bartle. His civilian job was full time Boy Scout District Executive. He founded the honorary scouting camping society, The Tribe of Mic-O-Say and his tribal name was Chief Bartle.
Lamar Hunt told the story of the name selection a number of times.
Next you're going to tell me the Chicago Blackhawks don't have to change their name just because they're named for the 86th Infantry Division, the Blackhawk Division, of which their founder was a member. I'm waiting for the Parris Island rename demand, named for a British Colonel who was a slaveholder.
