At first thought, I picked Holyfield. Then I thought about it: in my opinion Walcott hit harder (he floored Marciano), could match him or surpass him in technical skills, was faster, and was one of the few people who could match Evander in the area of conditioning. I would pick Walcott by decision. My dad said he was robbed in the first Louis fight (he was there). I have no opinion on that, since I never saw it.
