Lewis. Besides his size Lennox fought tall and was a master of distance better than any heavyweight in history. Rocky just couldn't get inside without eating serious punishment. If he did get in there Lewis ties him up rinse and repeat. Lewis KO 4-5 rounds.
Lewis KO 2. Too big, too powerful. Rock eats some uppercuts and a few rights before getting dropped for good.
I kind of see it like this also. But I guess I think Rocky's workrate will tire out Lennox the second half of the bout & maybe that's enough for Rocky to pull out the close nod. Lennox did get sloppy in there the second half of his fights. And like most heavies, not many late round ko's. And if Marciano makes it to the second half of the fight, he will definately get Lennox off his pitcher's mound and that's by far the most effective area Lennox liked to set up and work from. But Rocky has a lot more endurance than a Mavrovic--another tough guy that prepared well for Lewis. I think Lennox is going to miss that right hand over the top because the guy gets so low in there. He was like a crab. Lewis missed a lot of nice right hands he threw against a few other guys that did fight him low--Billups and Ocassio. The later bad back version of Rocky that fought Moore and stood up a ton is not beating Lewis. It has to be the youthful version and straight up guys are in trouble against a Lennox Lewis anyway. Those pre-fight preperations and superb conditioning are a problem for Lennox. And guys did set traps on Lewis and ko'd him. I think it might boil down to the right hand of Lewis. Can he land it clean on a guy that low or at a range different from way on the outside? Does he hurt his hand bouncing it off the top of his head and not the chin like he aims for? The jab wins the rounds and maybe cuts him Rocky, but like roy jones says, the jabs don't ko the other guy. And he also points out a jab is the easiest punch to counter and Lennox did stand straight up admiring his work sometimes. I think it's a terrific 3 fight series and it goes 2-1. Neither guy is going to be able to pull off all of their assets against this opponent without their own faults/disadvantages coming into play one time. I definately see a scenario where Rocky does not catch him and cannot deal with the size and accuracy of Lennox Lewis. And I see Lennox leaving open windows sometime during a fight for a finisher like Marciano to capitalize on.
