Bruno was actually out boxing Lewis and busted him up with the jab. Rahman and McCall managed to put Lewis down when they landed the right hand so how did Bruno not land his right hand? And Bruno was regarded as a much harder puncher than Rahman and McCall. So in theory, should he have caught Lewis cold, Lewis would have went.
Bruno never threw a harder punch than the punches McCall and McCall KO`d Lewis with, Rahman would have knocked Bruno out. Lewis was caught with a couple of rights by Bruno, but was moving away and Bruno`s rights weren`t sharp enough to do damage, Frank didn`t really throw many rights against Lewis and hardly landed any, Manny Steward studied Lewis`s sloppy display against Bruno and Tucker and noticed how open he was while throwing his sloppy right hand, so he trained McCall to time Lewis`s right hand and to throw his right when Lennox threw his, and that`s what happened adding force to the punch, if Bruno had done that he would have knocked Lewis out, but he didn`t have a trainer like Steward in his corner and we saw how much Lewis improved after Manny started training him, he beat McCall in a rematch and beat Rahman in a rematch, he didn`t train properly for their first bout and he wasn`t trained properly for the Bruno fight, Bruno`s jab didn`t bust Lewis up they were just decent point scorers, Lewis stated landed his own jab in the last couple of rounds, awful fight.
Bruno was Just Kind of an unlucky guy and didn't have that much of a killer instinct. Most of his losses were fights where he was doing very well and looked like he might win and then he would either: let a golden opportunity slip away, lose his concentration and get caught, or gas out at an unfortunate moment. That's why he was such a sympathetic character for British fans. They loved him even though he lost because he was a good guy with talent and skills who just didn't have things go his way. He just wasn't mentally "ice cold" enough to be what he could be. He was too human
He landed a big right hand in the third which shook Lewis. There are a lot of variables involved with one-punch knockouts; not necessarily "luck", but the stars have to align like they did for McCall and Rahman. Bruno just didn't land the right punch at the right time against Lewis. The same goes for other big punchers that Lewis faced, who on paper hit at least as hard as McCall and Rahman. I don't think Bruno was a massive one-punch guy anyway. He was very strong and heavy-handed, but elite fighters took his power, and the 2nd tier fighters he faced like Williams and Coetzer generally extended him to the later rounds. McCall actually has a better list of knockout victims (Lewis, Akinwande, Seldon, Damiani) even if his KO ratio isn't as good.
Lewis was ko`d by Rahman because his hands were down and he bounced off the ropes forward into the incoming Rahmans punch, plus his feet were stuck to the canva as his body bounced forward of them, he was completley off balance with no solid base and in fact Rahman legs may have also swept Lewis`s as he moved in and landed the punch. Bruno had a longer reach I think also.
Lewis had his own " lottery punch " and, that one was laded with him in retreat, with the camera angle I saw the fight on showing his eyes weren't even on the target.
Bruno was not a combination puncher, never had a killer instinct and never followed up after hurting someone. Lewis the one and only time he hurt Bruno, ruthlessly finished him immediately.
It was the same with Tyson, he had him wobbled in the first round in 89.But he couldn't seem to follow through. But it proved how hard Frank could hit .
He was similar to Wlad in the sense that he didn't want to go on an all out attack in case he got hit back. In the Lewis fight his over aggressiveness is what lost him the fight when Lewis countered him.
Lewis would have known that Bruno was a dangerous puncher, and was probably more wary of his power than McCall or Rahman's.
