What happens in this scenario-
A fighter in another promotion has enough of a name for himself to have sponsors, many with a longterm deal.
UFC signs said fighter, but fighter has a contract with sponsors not approved by UFC. What happens here?
They (Zuffa) have no fucking clue dude. Seriously. This Reebok deal is the epitome of the way Zuffa conducts business...unethical & scummy. They figured they would sign the deal first, then announce it to the world w/out informing the fighters of any of the details. That way, the fighters are locked in and Zuffa has pitched their bullshit of "we won't see a dime...this is 100% for the fighters...they're going to make more $ w/ less hassle....etc." Therefore, when the fighters are finally told the details and realize how badly they're getting fucked, one of two things would happen: 1) they would look bad for "whining" because Zuffa has already swayed public opinion to their side, or 2) they have no recourse because what's done is done.
Zuffa knew fighters and managers would lose existing sponsors between Sept & now...they didn't give a shit. They knew that they hadn't thought thru a logical way to allocate the money to fairly compensate everyone on the roster...they didn't give a shit. It was a totally short sighted deal, made out of greed. Zuffa will make truckloads out of this on the back end of this deal, and thru solo sponsorship deals w/ Reebok. They didn't (and still don't) give a fuck who gets hurt in the process. And they still have no idea how they're going to distribute the money fairly. Typical Zuffa...sign the deal, let's get the money, and then wing it.
The ONLY reason they changed from rankings to tenure, is out of fear of this lawsuit. My guess is, internally fighters are asking questions and voicing complaints. And Zuffa is afraid if they don't do something, there will be a fucking stampede to join up with Quarry, Fitch, etc.
