The fighting style of Jack Dempsey and Mike Tyson was very exciting. Carlos Monzon was impressive, too. He always was cool and clever when being attacked.
James Toney. How a (sorry James) fat middleweight could stand and fight with a fully-fledged natural hard-hitting heavyweight in Samuel Peter in their 1st fight (and win IMO) really was astounding, testimony to his pure skill.
I know people have favorite fighters for many, many different reasosn, but for me, what you describe is what makes these guys my favorite fighters (Sanchez, Leonard, Monzon, Chavez, Arguello).
I perfer the swarmers, the Rocky Marciano's, the Joe Fraizer's, the Henry Armstrong's, the Carman Balisio's the Gene Fullmer's ete.
...............Well, Sanchez of course. It was like you could see the wheels in his head spinning, and you'd watch him probe for weaknesses, find it, and start exploiting it bit by bit, never in a rush. While he wasn't the most exciting fighter, I'm fascinated by the artistry Napoles brought to the table. Always right in front of his opponent, but somehow rarely got hit, and was right there popping shots back in their faces. His unusual level of calm was intriguing.
Sanchez was a joy to watch. I'm still in awe of his stamina deep into the late rounds of fights. He never looked exhausted. Yes, he was extremely controlled with the way he went about his business.
My first 3, actually. I'm also in awe of Joe Frazier's constant CONSTANT full body movement, constantly stalking, moving his arms like a maniac, landing those hooks. How could he keep this pace like he did?
Gene Tunney's. He was always on a swift, accurate, punishing offensive mode, but with his defense perfectly in place. Fluid combinations behind a hard jab while disrupting your opponent's rhythm. Great stuff. He was way ahead of his contemporaries in technique employed and always did the right thing in the ring.
Wihtout a doubt, Ricardo Lopez, Salvador Sanchez, Pernell Whitaker, Jack Johnson, and Roberto Duran. Their styles never fail to distract me, they are works of art.
Aside of those two, I´m mostly attracted to either counterpunchers like Hopkins or Schmeling or swarmers like Armstrong.
...........The same is true of Napoles. Neither expended more energy than they had to; no wild, meaningless flurries, no wasted movement. Just a brilliant sudy in minimalism, perhaps more in Napoles' case.
