I like the name redtails, it could go to anything too. Like a fox or a hawk or a fighter plane. They're all pretty cool "predators". Of course, I think there are way too many bird logos in the NFL, with the Falcons, Eagles, Seahawks, Ravens, Cardinals...
Rick Reily wrote a decent piece recently about not changing the name, and the main thing I agree with him on is that it shouldn't be "white" people who are upset over the use of the name and that appears to be the main backers of a change of the name. Seems like more Native Americans have more issue with chiefs fans dressing up and the tomahawk chop.
I hate chiefs fans.
