Both Mike Brown and Uriah Faber have acknowledged Aldo as one of the best 145 pounders in the world. He'll murder brown WHEN they fight, and if Uriah's hands ever recover I think that would make for a great fight.
I mean hes has to be a decent fighter, you dont just beat the likes of Yves Edwards, Jeff Curran and leonard Garcia unless you know what your doing. But hes definitely not on fabers level (contrary to their record) without a little luck. People will see in a couple of months when they finally announce Brown vs. Aldo. Luck will have no place in that fight.
