One of the themes of this Dodgers off-season has been to bake as little risk as possible into the cake, to patch every hole before it exists.Nowhere has that philosophy been more obvious than in the team's moves to water-proof the bullpen, which is never entirely possible, of course. Many other – if not all other – clubs might have brought in on a veteran or two to complement closer Kenley Jansen and the returning relievers from 2013.
