Lewis would lose to prime Ali, no doubt in my mind. If he lined up fights with the others would get KO'd by 2 or 3 others, just not sure which ones, it's just a statistical prediction based on their greatness and his chin.
I never said I didn't give Tyson a chance. I give Tyson a 30% chance. Lennox is too smart for him....but 1 in 3 or 4 fights he may catch him with a powerful bomb that knocks Lennox out
I would give some non - ATG's like Ibeabuchi, Corrie Sanders or Vitali a better chance against Lewis than most of the ATG's. If Lewis' fights with Mercer, McCall, Rahman, Vitali indicate how he could be beaten, it would seem like either a monster punch or a prolonged brawl with an iron - chinned fighter would be the most likely ways how Lewis could lose.
From the list I would struggle to name (with total conviction) more than three or four at best who I'd favour against him prime-for-prime. I'd pick Holmes and Ali to outpoint Lewis, but they'd be hellishly close contests. Lewis has the power, strength and skill but because of Ali and Holmes being so durable it's difficult to see Lennox stopping either. Lewis' tendancy to drop off slightly during spells of fights also might cost him against these two, if he kept up a very high workrate throughout he'd have a good chance. Tyson, Liston and Louis would have a 50/50 chance but I'd favour Lewis to beat the rest, despite a few toughies amongst 'em.
