Povetkins KO of Perez shows he has power that one punch KO power. Id also say that Povetkin and Ortiz both throw very good body shots too. Fury obviously has power given his size but is more likely to wear fighters down with repetitive shots to get a stoppage then a one punch KO, which as a heavyweight could be a problem.

Fury was lucky in that fight. His scored a KO with an illegal punch and if he was not to get DQd it could have gone to the cards for a TD and I think he was behind on the cards. I havent watched the fight in a while but if I recall correctly Cunningham more or less punched himself out, well between that and Fury leaning and wrestling him he looked out on his feet by the time of the KO.
