Although the starting rotation is still a mess, the bullpen seems like a more promising area for the Dodgers to make strides. Even with the departures of Kenley Jansen and Joe Kelly, the Dodgers have plenty of relief arms to work with. Even fringe starters can contribute as relievers, as Brusdar Graterol has proven to be. Last year, he spent time in Triple-A, where he developed his mechanics and added a cutter to his repertoire. While it would have been nice to see him pitch more, Graterol may need more minor league experience before he becomes a viable reliever for the Dodgers.
