Who Wins In MMA: Lesner or Fedor vs Big Show?

1st off, people always make up these crazy fights and I always think its dumb. I never even look at the threads but this is a real one for me. I ask this because my brother use to be a big WWE fan and we were watching Lesner vs Mir. After watching it I asked my brother who he thought would win between Lesner & Big Show. I already knew what he would say. He thinks that Big Show is too big for him. Now let me break this down for everyone who thinks that wrestling is a joke and they cant hang with the real thing. These guys are elite athletes as you seen by Brock. However, I think most of them would get killed in a real fight but some guys are different. Some guys like Brock have real backgrounds in Wrestling or whatever. Then there are 2 guys like Andre "The Giant" and "The Big Show" who are truly superhuman type men. When Andre was alive everyone talked about how the wrestlers truly feared him, that he might snap one day because his strength was out of this world. Even Hogan was really scared of him off set. People in his hometown talked about how they saw him flip over a little car. I dont think some fans truly appreciate the size of these guys at 7ft, 500 pounds, with the biggest hands in the world. They could rip a guys head off. I dont know how a fight would play out with Big Show & Brock but I wouldnt just downplay what the Big Show could do. I just threw in Fedor's name for the topic but we never talked about him. This isnt boxing. In MMA, the big show could use his hands and grab you. It wouldnt be like Valuev trying to box. He's also got way more size than Valuev. Now you could say that Guys could take him to the ground or do leg stuff on him but I dont think that would be as easy as people think. I could also see him just grab Brock by the face or throat with those big hands and basically manhandle him. A punch isnt really going to hurt him and you cant slam him. I think he's probably stronger than anyone over there. It would just be something that I would like to see. This isnt a Kimbo situation. The size & stregnth would be apples & oranges. On top of that, Big Show is a true athelete. He's not just big. He can move. What do you guys think? I think some of you would think this is nuts because you really dont get how big, strong, and athletic a guy like the big show is. If you dont understand this size of his hands and how physical he could be with it, you wont appreciate this question
