Try 8 million + PPV points. And if he won against Jones, he could easily get another pay bump. That's not even taking into account all the millions he missed out prior to the Jones fight because of this contract disputes. The difference really isn't as big as you think, and he would have secured an actual legacy in MMA even among the casuals. His legacy among the casuals now is a meme of him getting KTFO, since the UFC own the rights of most of his highlights and you know they'll bury that shit 10 feet underground.
Also, it's laughable how brainwashed people like you are by your UFC and Dana hate that you take any dissenting opinion as shilling for UFC. I couldn't care less if UFC goes broke and Dana gets thrown in jail tomorrow. Can you say the same about Francis? I don't think so. One of us has someone's dick in their mouth, and it sure ain't me.
