Some fighters that come to mind. Vladimir Vichris. Sprott was outboxing the guy for god sake. Oliver McCall of course. Have to have the stamina though, Akiwande and Seldon both failed there.
Foreman wasn't particularly difficult to outbox either. Tommy Morrison prepped to outbox him, watched the Young fight with his trainers... And pulled it off.
What about Evander Holyfield? particularly the old version. Evander seemed to struggle with the boxers and movers like byrd, Toney, Donald but had less problems with big punchers who relied on power.
I thought Herman N (not even going to attempt it ) would outbox him after seeing him fight malinaggi but Urango put alot of pressure on him
Herman Ngoudjo did pretty well first few rounds then after that monster left uppercut form behind urango. he didnt look in it at all. only much late did was he able to get back into a bit and that was like round 10. good example of the crude slugger outpointing the smooth boxer
That uppercut was gruesome any other light-welter i think would have went down and we would have knockout of the year. Think i read he either broke his jaw or dislocated it props to Herman taking all those shots afterwards and still staying in there
David Tua takes the cake. He often landed late, but he was outboxed in every meaningful fight he was in.
