Sorry, but Fedor is regarded as the best fighter in the world, not Brock. And I mean right now. You might feel that Brock could win, or is better because of the 4 fights he's had, but no one in the legitimate mma world agrees with you. I'm not saying you don't know anything about mma, because you might, but if your going to call others UFC fan boys, you better have a knowledge of what the mma community feels about a issue as big as this. Most people are angry with Fedor for not doing what it takes to fight in the UFC, but hardly anyone would say that Brock is a better fighter, or that his record is better. There just isn't enough data yet to say that, Brock is a newb in comparision to guys like Fedor, or Miguel (who I think should be reagarded as the #2 lb4lb in the world with GSP), or GSP, or even Silva for that matter.
Fedor is the one with nothing to prove. It is unfortunate that we may never see that fight because it would be great, or if we do see it, Fedor may be past his prime, but right now, Brock is the one trying to eclipse Fedor, not the other way around.
