Bryce Harper is almost certainly not going to be a Dodger and Manny Machado was never going to be. The Dodgers traded for a catcher, yes, but I would go out on a limb to say Russell Martin was not the one you had in mind.
Regardless, it has not been a bust. The team did add Joe Kelly, Martin, some minor league players and an international free agent with the offseason a few weeks from coming to an end. There is still no way to predict what will happen but there are some rumblings around the league that pertain to the Dodgers and they are all worth note.
