Juan Laporte rarely gets mentioned. Faced just about everybody: Salvador Sanchez, Eusebio Pedroza, Wilfredo Gomez, Julio Cesar Chavez, Azumah Nelson, Kostya Tszyu etc.
Oliver McCall. Never knocked down or even buzzed by Tyson in hundreds of rounds of sparring. Never knocked down or seriously hurt in his professional career despite facing a who's who of massive punchers.
He lost a decision, but never went down. Later, the decision was overturned and it was called a no-contest. See the documentary: HBO "Assault in the ring". [ame]http://www.youtube.com/watch?v=zP2z6yrQFSo[/ame]
That was a very sad documentary. Panama Lewis also worked Roberto Duran's corner the same night when he badly beat Davey Moore.
