They aren't literal teams. They are just using it for advertising. I believe it is "Team Metro". They have a partnership with the UFC. I believe Cain, Edgar, JBJ and Faber are part of it. Metro PCS is a cell phone company.
I think that is what you are talking about.
Yes it is. I see now. So other than advertising theres no real point of these teams? I thought there was more to it.
