The sports "use case" is complicated by the fact that RFs don't work that well with long lenses. If you had a sports situation that you could shoot comfortably with a 90mm lens, then you could make an apples-to-apples comparison between RF and SLR systems---but how often does that happen?
Then there is the problem with camera shake and depth of field with long SLR lenses. Given a choice between using a telephoto and getting closer to the subject most people would choose getting closer. It's all a trade off.

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
