Cliches become cliches for good reasons. USUALLY. ...For instance, Bulgarians do not make great goat cheese. Bulgarian goat cheese is slightly above average, no more, no less. But that is neither here nor there, I don't want to get on a soap box and open up that can of worms again.
Tyson was greater prime vs. prime comparing him to Foreman. I think it is easily Mike being greater, but stylewise Mike might have had big trouble with George.
Any source material for this ? I can't see any reason why he would have done. Clay/Ali beat guys who beat Machen.
