That's right... Zuffa should get out while the gettin's good.
They've made multiple tens of millions, but mostly due to the fact that they've kept costs low and prices high because of the lack of competition.
Just look at the competition that will arise over the next year or so in the United States:
MMA will never rival the NBA, MLB, NFL or any other major sport in popularity.
Their costs are going to have to go up to compete... their market share will definitely come down. Not to mention... the market is going to change significantly if someone like HBO just decides to hold one-offs like Silva-Ortiz that pay each fighter 3 million dollars each.
Sell now. The UFC will never be more valuable to a potential buyer than it is right now.
