Moreover we've now witnessed, two times in quick succession with Morin and Magill, the reason to open a 40-man spot without necessarily filling it. It's already been stated that to remove a guy from the active (25-man) roster, if he has no minor league options remaining, then he has to be removed from the 40. That is independent of a decision to add someone else to the 40 - because it's not a step that is easily reversed later on. If the guy you want to bring up to the majors to replace him is already on the 40, it's fine to leave that empty slot for later. I applaud our FO for cutting two guys who they determined were the ones to cut, 40-man considerations be damned. You don't do it lightly, but you can't let fear of losing an asset drive every decision, especially a small asset.
