@Hussar, I don't understand what you're arguing. I can't speak to baseball, but the rules of cricket don't define spin vs fast bowling, nor when to use one or the other. They allude to "leg theory" (bodyline) only obliquely, via the rules around dangerous bowling and field placement. They don't say anything about the difference between a player who is good at batting, one who is good at bowling, and an all-rounder.
Yet cricket teams manage to arrange batting orders, choose bowlers, make decisions about spin vs fast based on player skill, condition of the pitch, condition of the ball, etc. Making those decisions is part of what it is to play cricket. The rules for Classic Traveller have tables to roll on for patron encounters and say that it's the referee's job to decide what the patron wants. The rules for Burning Wheel say
choose a setting and situation and give some advice on how the participants should go about this. The rules for Cthulhu Dark imply that something similar needs to be done; choosing Boston c 1930 as the setting is part of what it is to play Cthulhu Dark. Just like a cricket team needs to choose who to send in to bat, who should bowl each over, etc. I think most games require participants to make choices, and those choices affect the way the game unfolds and produces its results.
Now maybe every game of baseball is near enough to identical to every other - I don't know, it's not a sport I know very much about. But not every game of cricket is the same. From the rules of cricket you can't reproduce any given match. That would depend on the particular players, their choices, plus external factors like weather, pitch condition, etc. The same thing is true, mutatis mutandis, for Australian football (the only other field sport I know much about). And it's true for RPGs also.
I don't really see how any of this is controversial.
