Defense coming forward, counter right hand to the jab, economical accurate puncher, vicious body attack sharp combo`s inside great at cutting off the ring and so on, not bad at all according to clever cloggs here.
Chavez was from the Old School. He broke you down body and then head. A master at cutting the ring. Precision on the inside. Always relaxed. Iron chin. Heavy hands.
His professionalism in the ring always ready, adaptable, chin, underrated defense, endurance and just great at the basics just watching a single fight it is hard to see why he stands out but the consistency of his ability to fight his fight no matter what style is something else.
Combination of Several attributes. Very good but not great power that carried into the later rounds Great stamina and work rate Great punch selection, timing(especially on his right hand) and consistent bodywork Agressive but Solid, fundamentally sound style that influenced an entire generation of Mexican fighters Subtle defense backed up by an iron chin Relentless and absolutely determined in his prime. Duran was more of a "genius" and more talented but Chavez was an absolute workhorse
Something that nobody's mentioned, but personally I have a great deal of respect for top fighters who get in the ring often. Up until his early thirties, he did that.
In a nutshell ..all the above. The solid Chin ,stamina, defense and determined. Duran seemed More emotional in the Ring as well at times, Chavez was like a machine.
True You can really see Chavez's style in Marco Antonio Barerra. Yori Boy Campas looked even more like him, on the surface, but lacked Chavez's defense.
He was an authentic made in Mexico (TM) little big man, a literal perfect fighting machine in body and in spirit. He also cut a good amount of weight early in his career, didn't he? Good size, strength and physicality at the lower weights he fought at.
Campas had that authentic Chavez block head/chin though, despite his complete lack of effective head movement and taking flush power punches to the face from the likes of a young Felix Trinidad & Jose Luis Lopez without ever going down... I don't know if Campas ever hit the canvas throughout his entire career?
He probably did later in his career. He took tremendous flush shots from Felix Trinidad, his head was snapped back hellaciously.
