For me, probably Audley Harrison. But i guess for others it would be Henry Tillman or Tyrell Biggs. Does not need to be a gold medalist, just an Olympic medalist in any weight class.
Biggs and Tillman never impressed me too much in their Olympic performances, and I think they both accomplished about as much as they could in the pros. I'd have to think about other fighters... McKinney is the first to come to mind, but I feel like the same thing applies to him.
I thought for sure 2000 US Olympic silver medalist was destined for greatness. Instead, he went down the wrong path and pissed his talent away on coke. The guy was an outstanding fighter when his head was on straight.
