Boxing: Nikolai Valuev
Called “The Russian Giant,” Nikolai Valuev is to boxing what Andre the Giant is to WWE. He stands 7’ tall and weighs 328 lbs, making him a behemoth in the ring. If one of his punches land on you — you are guaranteed knocked out.
Valuev is not just a publicity stunt for the sport, though, because this guy can throw some serious power and technique. He has a 50-2 record and is, as of this writing, the biggest boxer to ever become champion. Before his left the sport, his last major win on the ring was opposite Evander Holyfield.
