8 round fight. Both in their early 20's. Who wins?

Stevenson was one of the greatest amateurfighters of all time. I haven´t seen him fight though, so I am not sure of his weaknesses and strenghts. My gut feeling tells me Ali wins this one. He is one of the two greatest heavyweights of all time and I cannot see an amateur defeating him, no matter how good and talanted this guy was.

Stevenson let a bleeder like Vysotsky beat him;that's a problem in my book.

ali ko's him in two.

Ali Would Bust Him Up Bad An Early Tko For The Greatest
