I think Larry Holmes would be undefeated aswell, obviously he would still have alot of trouble vs prime Mike Tyson. But i still think he has the right style to beat Mike Tyson.

What about the 60's version of Muhammad Ali in the 70's ? would he have ever of lost ? as much as i don't like him, i actually can't see him being beat by Frazier, Norton, Holmes, Berbick, Spinks.
