Current Best Pound for Pound MMA Fighters

What is P4P....? To me its a fighter that can dominate two or more divisions. Give up wieght to his opponent and still be dominate. The best example is Dan Henderson these days.Either fighting Andy Silva at 180.lbs or beating Fedor at heavywieght then brawling with Shogun Rua at 205.lbs Thats my idea of P4P. Unfortunately Mr.Henderson lacks diversity in many areas of the fight game. Thus he fails to be in my top 3 P4P.Should Dan conqueur Jon Jones... my list changes. What we have today in MMA is a opportunity to actually find out who is better...Jon Jones or Andy Silva? They NEEDED to fight in 2011. Why did Silva move up to 205.lbs a few times to beat up Irving Mitchell and Forrest Griffin IF HE DIDNT PLAN ON fighting for the belt??? Instead... the UFC gods call for GSP vs Silva. WHY??? We have a SUPER SHOWDOWN with Jones vs Silva all ready to go. That sure would settle the number #1 and #2 P4P debate.
