Hendo does the testosterone replacement so it's hard to judge. For me, the hendo/Shogun fight was so close that I gave it to Shogun based on "if hendo didn't have the testosterone replacement, would he have survived the last couple rounds?, would he have done as well in the first few?"
Either way, all time rank, I'd rank him pretty high based off his ability to move through weight classes and beat the top fighters. His win over Fedor really catapulted his all time status. I also give it to him based off the fact that he fights rather than tries to win off points and avoid fighting.
