I must say, that coming from a younger generation and not having seen the fights myself, the only things I have heard about Mohammed Ali are all good. Although it would not surprise me to learn that the fights were rigged, it is still disappointing to think that a champion like that would resort to such things.
Having said that, cheating in sport has become so commonplace that one just needs to remember the recent doping scandals in cycling to realise how rife it is.
