Maybe i'm a fan boy but i've watched JDS spar with Shogun (granted Junior has improved alot since then) and I think that Anderson would hand him his first KO loss if the two ever fought. Unfortunately it will never happen..
Imagine if Anderson beat GSP, Bones and JDS and then retired like a boss.
I don't think Andy could beat the big wrestlers in the HW div. but I definitely think he'd beat the strikers.
