Good points Diesel those guys really punished Ali but he found ways to beat them in one fight or the other.They were bombers but Ali had decent power himself which was part of what made him dangerous...As you you've said,Tyson is most dangerous in the early rounds and I got Ali being cagey enough to survive the early rounds and..dragging Tyson out to deep waters,as the saying goes,tiring him out and knocking him out late in the fight.
The way I see it,nobody calls Rocky Marciano The Greatest because he didn't come up with the title for himself.I think if he had it would have stuck and would have been forever married to his name...To many,Marciano is actually the greatest because he beat all his challengers and retired undefeated but then there are also those who will pick apart his opponents which includes men such as Joe Luis who was quite old and washed up by the time they met in the ring.
