My own thoughts go something like this..

Lennox poses a sizeable problem to George simply due to his accuracy and power. BUT Lewis had a lot of bad habits too, especially before being KO'ed. Young George can't box worth a piss, but he can hit like a Sherman tank. Lewis liked to stand up tall and he didn't fancy running. Young George has a serious shot of connecting with something barbaric and savagely ending Lewis's night.

Old George probably gets beat up pretty bad against a prime Lewis. There's always the one-shot wonder, ala Moorer/Foreman scenario, but I give that about a 5% chance of playing out. Dumb luck really.

Vitali I think has not been fairly represented in this matchup. Versus the old comebacking George, I see this a landslide victory for Vitali. Too tall, too long, and knows how to fight tall and keep guys at the end of his jab. George gasses and loses a UD. That said, I don't think Vitali stops him, just beats him.

The younger George versus Vitali.... well now thats a humdinger. I've never even seen Vitali hurt, but you gotta imagine the fella to do it is the 70's version that blasted Joe and Kenny into the stratosphere. An older, ill-trained Lewis smacked Vitali with some hellacious shots and Vit took them like a champ, but call me crazy, Lennox's big right isn't quite what the Houston hooker's was back then. Could Vitali have been smart enough to rope-a-dope and be patient and paw and jab and wait for George to gas? Maybe. Good chance of it, I think. But if he couldn't.... there's the guy that knocks Vitali out cold.

For the love of God, I want to see the Lewis/Klitschko fight finished. Oh but it WAS finished, Balboa, didnt you see? It got stopped on cuts! Not. Acceptable.
