MM is not giving himself up out there.
What I don't understand is that every fucking champ out there have that champ status to show off in hollywood (and everywhere else) yet only a handful are prepared to do that, Ronda, Chuck and McGregor being some of the few. Guess what those have in common?
Not saying it's totally their fault, but fuck it, time and time again it's been shown that Zuffa will only market you as a fighter only this much and the rest has to be done by you and your manager.
Some of them are smart - they're making a name out there among the mortals. Most of them though, they're just sitting on their asses or training their asses off, expecting someone else to do that for them. Guess what, it's not gonna happen - you want to be famous and make money, make a name, then you'll get some money.
Also, MM, well, the dude is one of the most boring champs I've ever seen and also, it doesn't help that he's tiny. Not that I care about size, but it helps to big, and if you're big, you need to market yourself a bit more. Conor or Ronda aren't huge by any means, yet they succeeded. Follow their steps.
