Vitali Klitschko (sp?) vs Holyfield.
Klitschko gets a lot of criticism, but I think he's pretty formidable. Huge guy that uses his size and weight well, I think I'm right in saying he's never seen the canvas, and a pulverising jab. He may never have really been tested given the calibre of his opponents, but that's not his fault.
He lost on a stoppage by Lewis, but that fight showed that he wasn't phased by some real power (an out of shape Lewis still hits like a train).
I think Holyfield's best tactic would be the usual one of butting, looking for a cut. Other than that, I think Vitali is simply too big and too awkward for him.
230 strict press @ 220; bodyweight+187 X 4 dips @ 180; 403 front squat @ 210; 10 000 push-ups.
