Been reading through all the comments, all have valid points, but the question was who is the best BOXER. in my opinion Ali was the greatest BOXER ever, i dont go in for statistics, how many fights won lost etc etc. its the way these guys fight, Without a shadow of doubt Ali was greatest alround BOXER of all time,His boxing ability was textbook, not street brawlers like most. He was a dream and a privilege to watch, Thats my opinion anyway.
