Sanders by quite a bit. Remember he flattened Waldo with no more than 3 lefts. He also rocked Vitali good several times with the same left. He's a bigger man than Haye so no shame in it. He's also freakishly quick for his size. One of those 'could have been' heavyweights to be sure. If he had better trainers and more interest in boxing.
Sanders, he could really crack. Haye has power too, but at heavyweight Corrie is on a different level
Definitely, like you said if he was devoted and had better trainers, that power and speed combination could have been something special. He had a pretty good chin too. Who do you think hits harder between him or Wladimir?
Tough to say. Waldo hits pretty hard as well and knows how to get his body behind a punch. I'd have to say punch for punch Waldo probably hits slightly harder. Bigger man n' all.
