Not so sure about this.
If Randy needed the money UFC would have probably given him a spot as a commentator or as one of those fight talk show host. Now that he actually went to help out the rival promotion, I don't think UFC will be too happy about it.
He could have taken an office job like Hughes and Chuck. But he can be apart of something bigger now. The rise of an organization. He can see that Bellator is on the rise. Why not get in on it? Randy has never been shy about going against Zuffa. He is one of the few guys that has his own brand and has name value. He doesn't need Zuffa.
