mwm5 said:swimming is pretty much exactly like track/field in this topic.
not every swimmer does butterfly, not every swimmer does back stroke, not every swimmer does breast stroke. very different techniques.
Exactly, techniques. Different techniques to perform the same athletic feat, swimming. There are similarities between T&F and swimming certainly, but I see more differientiation between the T&F events. Hurdles requires a pretty different skillset from Long Jump, and Discus throwers aren't runners. Marathoners aren't sprinters. Some are pretty close, like Discus and Javelin, but those are only in the games anyway b/c they were ancient Olympic events. I don't think either, certainly not both, would be in the modern games if they weren't traditional.
