Marvin Hagler: came forward on the balls of his feet, lots of head movement, killer left hook to the body.
Tua was kind of like Frazier in frame and in owning a devastating left hook that his entire offense was based around. Frazier was exponentially better at cutting off the ring and possessed far better head movement, and didn't load up and look for a one-shot KO like Tua did too often. Frazier was also in-shape more often and able to set a more torrid pace than did Tua (Tua-Ibeabuchi was one of Tua's only fights where he fought at a fast pace and threw a huge number of punches). As a result of all those things, even though Tua had more one-shot KO power and had a much better chin, Frazier was a far superior fighter. Shame, too, because Tua was lucky to be born with some awesome natural attributes he failed to make the most of. Frazier deserves much respect for not being born with tremendous natural gifts in a lot of ways but still becoming highly skilled for his style and making the absolute most of what he had.
The Tua-Ibeabuchi fight is one of the greatest heavyweight fights between the two of the greatest could have beens in the entire sport. I often wonder what the devision would have been like had Ibeabuchi not gone to jail.
Hagler could throw a left hook at times as he was known as a switch hitter. He preferred his right hook in southpaw stance though because he was right-handed
