See, I don't think they kept Kepler due to sunk cost fallacy (one of my favorites, as it were). I think they kept him because Larnach wasn't healthy, AK wasn't, they weren't playing Buxton in the field, etc.....they wanted depth. They have that now, but it is much harder now to do anything. No one makes trades yet, and no team just cuts a veteran that puts up league average fWAR.
