Who was the biggest and best guy Ali ever faced?Forman?He was at the time 6'3 and 220lbs.You could say Cooney but he really didn't beat any well known fighters at all.The truth is Ali never faced a guy that was as big as Vitali or Wladimir that had the skills they do to go along with the size and power.He fought Mathis who was 256 and when Mathis had stepped up he always came up short.Joe Bugner was the next biggest guy Ali faced at 230lbs.He was a fighter who if you looked at his wins and loses would think he was really something until you look at who he was fighting.3/4 of the guys Ali faced were under 215lbs and a lot of those guys were less than 200lbs.I just don't see how people are so sure Ali beats the Klitschko's so easily I am really waiting to hear a legitimate reason.
