Good match, I want to say Botha and he certainly could, however I think Peters was a bit more devastating. 60/40 Peters. but I'm still betting Botha.
Botha was more skilled but I fear that he was not 'cute' enough to avoid the worst of it and didn't hit quite hard enough to dent Peter. I'd like to think Botha would put up a gallant losing effort. Peter at his best was crude but very powerful.
