"Just put those guys in Long Relief or Mopup roles then."
Yeah, I guess this is probably the closest thing I could get to my desired behavior.
"Players on the 'rest' setting will come in the game once all non-rest players have reached their pitch counts, which sounds like what you're wanting."
Yeah, but sometimes I really DO want 'Rest' to mean 'Do Not Pitch'. I reserve it exclusively for pitchers who are not at 100%. If all the other pitchers reach their pitch counts and it's 2-1 in the 13th inning, will the sim bring in my 64% Setup A I'd prefer to leave resting, or my 100% Setup B who is listed as Rest?
"So you want to program Dusty Baker's long-man usage patterns into the game? Ask Micah Owings how that worked out for him, pitching once a month."
Personally I would only use this setting in the playoffs. During the regular season I don't care as much. But in the postseason, against a good team where even a 5-0 lead might not feel safe, I'd want to put this in effect.
