Naseem hamed as stated by emmaneul steward who went on to say that he hit just as hard as some of he heavy weights he used to train.
I was thinking the other day about Argentines. It seems like all of them hit hard along with decent speed. There is a lack of technical skills but they tend to have crude power. Sergio Martinez is the rare one. Although i feel his punching power is underrated by some.
Sillakh has been KO'd by Korobov and Beterbiev, with headgear on in the Am's. Beterbiev made him look like he was shot with a deer slug, after drinking a litre of Vodka. Just saying.
