What they need is one or two breakout players in the system, whether it's Rojas picking up where he left off in the AFL, or Bergolla shooting up the system and making the Show in two seasons, or someone else surprising.
A couple standout players showing up the next two years, and maybe a couple of those big arms making it into the pen as 7th inning guys, and they won't even have to push the luxury tax. Right now the farm is starting to deliver depth (both their own and trades, Stubbs, Sosa, Maton, Guthrie, Marsh, Vierling, Brogdon), but they need that breakout player or two that allows them to go cheap elsewhere or dump a salary.
