Was there any question about who would be number one? Conor McGregor just needs to defeat Dennis Siver this weekend, and he'll be headed off to face Jose Aldo in a stadium somewhere for the featherweight championship. That's huge considering McGregor has just four fights to date in the UFC. Of course, he's won all four, three by stoppage, and is a mutli-time performance bonus winner. Some will argue that McGregor has talked his way into title contention, but thus far, no one has been able to beat him in the octagon, so its hard to question his results.
