If you look at the standings, we are a half game behind the Orioles. If we miss the playoffs by one game, and we look back at the season and factor in that IF Sanchez were pitching would have most likely won that one game that cost us a run at the postseason, would you call that good management?
See, I just can't view the world that way. There's absolutely no way to know what would happen if a different decision was made.
Management is making decisions and living with the consequences. If things go well, some will consider it good management. If things go badly, some will consider it bad management.
So, if they leave Sanchez in the rotation and they miss the playoffs by one game, because Sanchez has a horrible start, is it bad management?
