Haney has never fought nor beaten anyone like the machine that Chavez was in his prime and at his best. Chavez by KO somewhere between 5-8.
But his size did not help in any other way. Weight bullying is a myth when matched against skilled fighters. Maybe. Nobody can really say Loma would have KO'D Haney if they were the same size. What we do know is, Haney’s size did not matter. There is a difference between someone that shrinks down and rehydrates than someone fighting at their correct weight. The natural guy will be much stronger. Sure Haney weighed 160, But a 160 Haney compared to a 160 Golovkin isn't a comparison. G is much, much stronger than Haney. You think Loma would have had the same success against Golovkin? Loma would be lucky to see the 4th round.
Chavez downs a bottle of Bud, smokes a huge stoogie, then proceeds to go to Haney's ribs with a vicious left hook and breaks him in half and leaves him in the middle of the ring pissing himself.
Well he didn't run over Frankie Randall as he was beaten up twice. His attempts at the welterweight title ended up a draw against Whitaker which was a robbery , and he lost to Kosta Tszyu and Del hoya at 147, and badly. Haney isn't on Chavez level but he'll be far bigger on fight night with a 4 inch reach advantage and a Haney win is not out of the realm of possibility. Likely no, but its not crazy either.
