The Braves have already been forced to retire Chief Nocahoma. The Indians are under fire for Chief Wahoo. There's another thread around here that seems to indicate that the Blackhawks are safe since they're named after an individual and not a tribe, and the Indians don't seem to have a problem with them. But the Chiefs and Arrowhead? I'm keeping my fingers crossed.
