Why do we need MMA Weight Classes?? Let Fedor and Silva fight it out!?

[Tony]

Doesn't this defeat the purpose of finding who's the best fighter in the world? If there's an arguement of the best pound for pound fighter, let them duel it out and be done with it. Example, Fedor usually fights opponents 30-40lbs more, so what's the big deal if Silva is outweighted by Fedor by the same margin. In martial arts, you are taught that size means nothing.

If those two are ever going to fight, they'll have to fight in a country where the MMA rules are less stringent/more lenient.

Fedor would completely demolish the guy...Fuckin Dana white would even let this fight to happen cuz he knows tha Anderson would get destroyed...Dana needs to stfu with all that best pound for pound fight.....Pride fighters>>>>>ufc......Nothing against Silva hes a great fighter, but he would get wopped bad.....Fedor can own anyone in the ufc whether its middleweight heavyweight or superheavyweight.....Guy is a fuckin machine
