Olympics and other competitive events seek the best. That's not really true at all. Look at swimming again for example, they have lots of rules related to what you are allowed to wear and how you're allowed to swim that all lead to slower times, but (hopefully) a more fun event to watch. The Olympics keep changing and tweaking the rules of all kinds of sports simply to try to make them more interesting and/or increase their popularity and viewership.
