I don't mean, which fighters have the deepest resumes, I mean fighters that have fought the most different styles? I say Jose Luis Ramirez is a good shout here. He fought the cold, calculating precision fighter in Arguello, the rough, tough brawler in Mancini, the explosive knockout artist in Rosario, the flashy style in prime Camacho, the intense swarmer in Boza-Edwards, the slick, defensive master in Whitaker, and his own mirror image in Chavez. What are some of your picks?
peter buckley. after 300 fights he has fought just about everything that has walked /crawled and laced on a glove at one time or another.
Muhammad Ali fought a variety of styles (Foreman, Liston, Frazier, Norton, Patterson, Holmes, Lyle, Shavers, Quarry, Foster, Moore, Spinks, Williams, etc)
