as of right now he is clearly the p4p best....he's defeated more top fighters, DESTROYED them, and hasn't lost himself in a long time
i personally have no doubt in my mind he is the best...he's ahead of both fedor and gsp...penn shouldn't be top 3 at all
What top level fighters has he fought outside
of his weight class? Here's a hint: it's lower than one. Silva is already a giant at the weight he fights at. Silva isn't even the best p4p fighter in the UFC, let alone in the world.
