Hearing a lot at the moment about "The Greatest Olympian".
Of course there is a strong argument for Phelps to be this person, but like many discussions, aren't people often thinking of the most simplistic argument which is, whoever has the most gold medals must be the best? But surely you are not comparing like for like. You can't compare a swimmer with a decathlete for example, but a decathlete is only going to get one gold medal at most. Now Phelps is clearly one of the greatest, but to say any more than that you have to be very specific about what you are comparing - which of course the media aren't going to. If you don't do that I would argue you aren't saying anything meaningful.
The argument follows on from this I think. If you had the potential to be the greatest athlete of all time, but had not even chosen a sport to be the greatest at, but had the ambition to be the greatest Olympian ever, I would suggest you should take up swimming. Another way of saying this would be to ask the question "how do you get to be the greatest Olympian of all time" and the answer is "well first you have to be a swimmer". I don't think that's fair on other sports and IMHO there does seem to be a large number of medals in swimming that could possibly be argued as redundant, or not sufficiently different to ensure that different people have to specialise in order to win them. Compared to the track for example, it is extremely unlikely to win multiple golds - didn't Lewis once win four? But that was four medals and that
was once. It is relatively common for a swimmer to get four golds at one games. So one swimming guy can be good enough to win at several strokes, but if not still gets the chance in team and medley events and relays. On the track, even the 100m and 200m are often not won by the same person.
To a certain extent you could argue that on the track it's a simple measure of who gets to the line fastest. You can pretty much have any sort of technique you like to get to the end. In swimming they have four different fastest. Of course if I were a swimmer I'd probably think differently, but to me it's not much different from having an Olympic backwards 100 metres or hopping 100 metres.
So when they say that Phelps is the greatest Olympian I would say that he may be, but he also had a huge advantage being a swimmer. You could easily argue that Steve Redgrave and the criminally underrated (in honours terms anyway) Daley Thomson are equally great Olympians for different reasons.
