Corrales wasnt bigger than floyd. If you're just going by length mikey has beaten plenty of longer fighters.
Roy Jones jr - John Ruiz? It's a cliche, but a good big guy usually beats a good little guy. However, there's nothing to say that an ATG little guy can't beat a good bigger guy. The above and the Mayweather/ Pacquiao fights already mentioned being good examples.
The old axiom is is that a great little man almost never beats a great big man. That means that skill levels being comparable, the little guy will almost certainly always lose to the bigger fighter. This applies to Mikey Garcia vs Errol Spence. For Garcia to have had a legitimate chance of winning he would have had to have been that much better in some of the categories. Was Garcia quicker, faster, stronger, longer, more powerful...……..???? If skill level was equal, what physical advantages did Garcia have to beat Errol Spence??? Garcia having added the pounds that he did, was not any of quicker, faster, stronger, or hit harder than Spence. Since Garcia didn't have a height and reach advantage, he needed to be stronger and more powerful on the inside, but being the smaller fighter moving up, he just wasn't. The Garcia-Spence matchup to me reminded me a lot of the matchup between Juan Manuel Marquez and Floyd Mayweather, where Marquez climbed up two weight divisions to fight at 147 lbs for the first time ever in his career. In both instances, Garcia and Marquez got clearly beat. Guess what people, anytime you have a matchup of comparable skill levels but one of the fighters is moving up more than a weight class, if you don't have any physical advantages over the bigger fighter, you're going to get beat pretty soundly. It just amazes me how some so called boxing fans will say that size had nothing to do with Spence beating Garcia and Mayweather beating Marquez. Sure they got outboxed from distance, both Spence and Mayweather had significant height and reach advantages in those fights where it was going to be extremely difficult if not altogether impossible for the smaller fighter not to get outboxed under such circumstance. If size had nothing to do with it, I ask you this, if it were Spence or Mayweather moving up two weight divisions to fight Garcia and Marquez respectively, would they have had the same success if Garcia and Marquez were the bigger fighters??? I say a resounding no, they would not have had the same sucees as more than likely Garcia and Marquez would have been stronger physically and punched harder, making it more difficult for Spence and Mayweather to keep those guys off of them. So many other variables to consider as well as Spence and Mayweather would have lost some quickness and speed moving up where as Garcia and Marquez accustomed to their weight class maintain their quickness and speed. If the tables are reversed, its a whole new ballgame people.
because Floyd is Floyd and Manny is Manny Theres a reason these guys sold over 4 million PPV buys fighting each other
The special physical traits about Floyd and Pac are also why Lomachenko won't be able to go past 140. He lacks the frame and power. It's not a question of his boxing ability, but physical disadvantages.
