He has power but he lacked the desire and discipline to carry it through. He was too heavy when he fought Lewis. He was overpowered by Ike Ieabuchi and I don't remember the correct spelling of his name before he went to prison and Tua never got a rematch but his opponent hit harder. George Foreman fought better with more control as an older man and he hit harder. Ron Lyle and Sonny Liston hit harder but he was always going to jail for beating up cops. Mr. Marciano though smaller had more control of his urges and unlike Tua, he was at the gym every day when he was fighting. The quality of opponents had a lot to do with how hard he hit.There are more guys that fought the who's who of boxing. Tua could have been in the company of these fellows and the numerous I don't have room for except once again because of quality, desire and discipline but he had the tools and didn't take good care of them.
