That was Teofilio Stevenson- great great great fighter, Would have happily fought Ali but is a loyal Cuban and quite the communist (ended up as Cuban Minister for Sport). He's have given prime Ali a run for his money IMO.

Also, in apart answer to the question - Ray Robinson had something like 200 amateur fights, only losing three, and then went straight into a 140 fight winning streak as pro. Seems pretty dominant in a tough era?
