Protecting an additional guy last week wouldn't have been entirely without consequence -- it would have guaranteed that player a 40-man roster spot into March, I believe. So they could have protected, say, Gilmartin, but then if/when they add free agents, contenders, waiver claims, etc., they'd have to cut a different guy from the 40-man and they couldn't use the Swarzak/Gilmartin spot anymore -- they'd have to cut Duensing or whoever. Now, most of us think there are still enough suspects on the 40-man to make it a moot point, but the Twins probably just didn't value any of the remaining Rule 5 eligibles as much as those suspects and having some flexibility with that roster spot. Heck, they still may need to cut a few of those suspects too.
