Black Hawk was a real person, not a tribe, and a ton of stuff in Illinois and Iowa is named after him (schools, bridges, etc). the Iowa Hawkeyes got their name from the same dude, even tho their logo is a bird.

if the logo is meant to be dignified portrature of one particular guy, as opposed to a generalization of a group of people, it just strikes me as different. and tbh ive never heard people raise the issue the way it was raised for Indians/Redskins/Braves/etc
