Right now I have Fedor number 1 of all time but I think eventually GSP will pass him. Hendo is currently number 5 on my list but if he beats Jones I would bump him to number 3 behind Fedor and GSP.
I love Hendo and he is one of my all time favorite but it does hurt him that he has lost to a few guys meanwhile GSP has avenged every lost and Fedor was unbeaten for 10 years. So to pass those two would be very very difficult.
Greatest of All Time
