2. Nikolai Valuev
Former WBA Boxing champion Valuev is an outrageously big man. The Russian fought at heavyweight and was one of the most difficult opponents to face in a boxing ring. Standing at seven feet and weighing up to 328 lbs, he was ludicrously imposing. 34 of his wins came by KO. This is a very powerful man.
Valuev was more than just a big man, however. He went 50-2 in his career, including a victory over former undisputed champion Evander Holyfield. However, that was a much older version of the former four-time champion. Valuev’s final loss came against Britain’s David Haye. He struggled with the mobility of the smaller man.
