You may be confused with what being a draw means, I'm pretty sure when people talk about the Lesnars and Mcgregors being a draw it's because the casual fans get excited for spectacle and cheap popular gimmicks which makes those fights sell more than the average UFC stars. Moussasi is more of a draw to the legit fans of the sport, the fans that will still be watching when the Mcgregors and Lesnars go away for good, the fans that get excited for good fights more than trash talk and hype. If the UFC wants it's athletes to sell themselves it won't take long before it's all WWE style characters acting like idiots, but I think that is the wrong way to go about things. Popularity in this sport is not about winning fights anymore that seems to be secondary to personality and trash talk. Mike Perry gets worked over by an average welterweight but because he acts like an idiot and talks shit on twitter his fan base is giant, it's actually kind of comical.
