I'll throw mine in there.
Colorado Stealth - As a Colorado resident i feel you can't go wrong with a lot of the suggestions so far. I will say the Cowboy theme, Wilderness/Animal theme, Rocky Mountain themes are especially fitting. But I wanted to throw out something different. The Stealth pays homage to the Air Force that has a heavy presence in the state. Plus they'll have sweet black uniforms.
Seattle Cyborgs - Seattle is a big time tech spot. I've always thought Cyborgs was a great idea for a team name. Plus you have the great alliteration that is all over Seattle sports (Super Sonics, Seahawks, Sounds, Steelheads, Seawolves).
Minnesota Drakkars - The Drakkar was the feared Viking long boat. We have stayed away from the viking theme in our two other opportunities with the Loons and Voyageurs. I think its time. A really cool viking dragon boat would be sweet.
Chicago Rhinos - I have no reason to suggest this except that I love the name and feel like the Rhino is an underused mascot. It'll make for a great logo. And it represents the tough 'broad shoulders' nature of the city.
Louisville Sting - I was wary of going the horse route on account of the AltFL's Stallions. I also didn't want to go the boxing route on account of the AltFL's Brawlers. But I think this is a good name for a few reasons. It has a modern NBA team feel (Magic, Thunder, Heat, etc). Many people have referenced Ali's "sting like a bee". Plus the bee is the state insect of Kentucky.
Detroit Hot Rods - Just a cool sounding name. I know a lot of people have gone the auto industry route but since they would be our first Detroit team it would be cool to go that way. I could see a sweet Black, orange and yellow scheme.
