In one of my old jobs, a colleague once tried to argue that Don Bradman, the Australian cricket player, was the greatest sports person of all time. His central argument? Statistics. Don Bradman, statistically, was so far ahead of his peers that he was undoubtedly the greatest cricket player who ever lived. I'm not sure this is an argument that can be settled with statistics.
So how do you judge it? By what competitions they won? Iconic performances? Cultural impact?
Obviously judging the greatest sports person of all time is fairly subjective, so let's hear opinions: who do you think is the greatest?
I have a couple of people who I think are up there: Muhammad Ali is the first one who springs to mind, just in terms of his impact. Another is Maradona, who I would say is the greatest soccer player who ever lived. More recently I think Roger Federer deserves a swing at the title. As does Michael Jordan probably, even though I'm not a massive fan of basketball.
Who would you say is the best?
