do you think ifbb want a big headed non English speaking Muslim as mr O? 
Phil Heath is way more marketable, can speak fluently, speaks English, is American
Plus phil Heath in shape is unbeatable despite being school boy level wide 
I disagree with Phil being more marketable. Ramy has mystique around him, being as big as he is, having a tiny waist, and just being a very polite humble guy. Phil argues with trolls on Instagram, blocks people by the hundreds a day, and lashes out at any criticism. Yes, he's American and speaks fluent English, but that's as far as his charm and charisma goes. How is he making bodybuilding better? I'm not saying that Ramy would propel the sport or anything, but Phil literally charges money for workout videos on a pay-per-view site. Cutler was probably the best example of what a Mr. O should be outside the stage and gym, and he tried to instill that into Phil, but Phil is a manchild who only thinks about his bank account. And ironically, if he followed Jay's footsteps, and became an ambassador for the sport, his bank account would thank him in the long-run.
I'd say if the IFBB wants to save bodybuilding, they'd do whatever it takes to groom Cedric to be the next Mr. O. He has a throwback physique, and given the opportunity, I think he would be great on camera and show people that bodybuilders are not idiot meatheads who lash out in a fit of roid rage any time they're told they're too narrow or their calves suck.
