One thats hard to peg is Holyfield.The version that kept his head and outboxed a viable returning Foreman.....or the broke down Tyson and walked through Moorer.

Or a question Ive always wondered...at the risk of being laughed off.Foreman??Which version.He was raw and primed in youth,physical ability in his first run but the comeback saw a superior thinker and great disipline with better timing.I think that version may have topped young Foreman
