If we're gonna call a team the NightClubs, then Miami should get it. Since Atlanta known more for being hot as hell anyway, we could call them the Heat.
Also, I dont know much about Milwaukee, but I dont get how the whole Bucks thing fits. They should do something related to beer, like the Brewers in baseball.
Something would need to be done about the Cavs too. Hmmm. Unemployment is really high in Ohio. We could call them the Cleveland Pink Slips.
