Right now the rebuild is looking a bit shaky, especially on the position player side. There really is no more help on the way from the farm in terms of impact position players for the next couple of years at least - if they want to improve, they are going to have to fire the money cannon at Harper or Machado, which is fine if those guys don’t go to the NYY, Cubs, Dodgers, etc instead. If they go elsewhere, the offense could struggle unless development ticks up (which is possible).
Position players from within who are potentially impactful are at the Class A level - Gamboa, Ortiz, hopefully Haseley, Bohm and that kind of looks like it at the moment. LHV is a wasteland. The rest are much more likely to be writeoffs- Quinn, Cozens, Moniak, Randolph - or low ceiling (though fine players) upside such as Brito, Grullon, Maton, Gomez. Etc until you get down to rookie ball.
