Lewis never really rocked Vitali. Maybe stunned him a couple of times, but not ROCKED. Sanders is the only one I've seen.
Yeah, Sanders had a unique style, really unpredictable and unstoppable when launched, plus he was a damn ****ed southpaw, with hands between the faster of the division, and additionally very accurate.... in fact, if he would have started boxing as a child, and exercised well during his adolescence, he could have stopped ANYBODY; he was a damn natural, even without a proper boxing education...he had an exceptional ring instinct, but most of all an enormous heart; the referee of that fight said that he never had the luck to see a bigger show of braveness. And Wladimir jumping for crazyness on the ringside is the cherry on the cake... he was really mental involved, spectating that fight.
I'd say he rocked him. VK had to hold for a few seconds. You don't see that often. He shook it off quickly, but he was definitely staggered by it.
But maybe Sanders never really had the muscle fibres for continued stamina, he was a very fast sprinter in his school days... sprinters excel in bursts and not stamina. But yea, I don't think many could top his "spurts" when he goes all out you better hope his engines runs out very fast or you will lay on the ground. (It often did run out) And yes, Sanders his engine can run out in 30 seconds. He didn't box full rounds so to say, just a burst there, and a burst here, maybe for 2 rounds.
I also loved how Vitali dived in head first against Sanders and suddenly he starts running away, you don't see that often.
Lewis at a few points in their fight. The uppercut, the combination at the end of the 6th, and I think a point where he walked onto a jab Chris Byrd also seemed to rock him with a bodyshot tht landed brilliantly
