There’s situations where is more important be fast than be a good photographer. One of this situation is making sport photos. Sport photos are very complicated for only one reason. All things are moving fast. Moving fast is a problem because you must calculate light very quickly and, usually, every photographer must do mistakes.
Sometime mistakes and confusions and.. errors are good, you can see the most creative photo when you changes light. But if you are a press photographer you must do a perfect light photo, so that’s because professional cameras do too many shots for seconds in this situation. One of they must be “correct” (or not).
