The thing that impresses me the most about Fedor...more than his incredible strength and great skill...are his intelligence and calmness in the ring. He doesn't rely on his physical attributes alone...he thinks, adapts, and dominates. That is why when people make Mike Tyson or "cyborg" comparisons....i think it does Fedor a great injustice. He is so much more than this powerful beast. He uses his mind just as effectively as his body. His calmness is also a huge asset...he never panics...always seems relaxed. That is why it will take someone who is both a fantastic athlete AND also a very intelligent fighter to have a chance against him. You CANNOT make a mistake against Fedor...one misstep...and he capitalizes immediately. No room for error. And as far as UFC's great hype hope...Brock Lesnar....please! He will win his share of matches because of his size and athleticism...but at the end of the day...he is a blockhead. They keep throwing these GIANTS at Fedor...and he is never physically over matched...the man is pound 4 pound the strongest fighter in the business. No one is unbeatable...including Fedor...but it will take a very special fighter or an off night for him to lose.
