This is actually a great call. I see absolutely no problem with this.
Eh, minimum PAs for stats like BA, etc was 5000, and players in the negro leagues had like half of that.
For a game with such massive fluctuations due to sample size, I have issue with that.
Now, in reality, I do not care about this at all. It doesn't really bother me one iota. But I do feel it was unnecessary, because it really doesn't change anything, no matter how much we try to change the past and our history.
