Please do not compare the skill set of Bob Sapp or HMC to guys like Kongo, Gabe, AA, Couture, ETC. It's an insult. When people have skills and a remarkable size differential, they'll win 95% of the time.
I was compairing Hong man to Lesnar.
I don't think Couture is any bigger than A. Silva could be.
And I think the rest are bigger but just like AA showed in his last fight, 25 pounds doesn't win a fight.
