"The only statistics they are allowed to incorporate are appearance-based, like PA/IP, and those are clearly meant as a proxy for health." I really disagree with that statement. You are trying to write your version of the unwritten rules. If a pitcher had bonus, say for 200 ip (a very, very common scenario) and he ended up with an 8 era mid year, but is healthy, can he (should he) file a grievance when he loses his rotation spot. I hardly think that PA and IP incentives and options are guarantees to be the starter, no matter what, as long as you are healthy. And who decides health? Rickie is much, much slower now because of his ankle/legs/hammy/age. Say he is pinch ran for, say by Shafer, and misses an at bat later in the game. Does he file a grievance with MLB Players Association? SRB, it may be true that you are right and the 99% are wrong. But you should consider your position carefully if you are in the 1%. Maybe you are wrong?
