Lol, he also competed on an international level during that time that did require drug testing and never once failed.
He "ran away" from the UFC to fight in organization that had better HW divisions and UFC fighter attempted to leave the UFC for the chance to fight the man that they (his peers and actual fighters) considered the true HW Champion of the world.
I really don't get you dude. Anderson is my favorite fighter too but what Fedor accomplished is unpresidented and unbelievable in a division where 1 punch can end it all regardless of how much more technically skilled you may be compared to your opponent, Just ask Volkov about that, or Stipe for that matter.
Belive it or not you can actually like and respect both guys for there contrabution to the sport.
