Piggybacking on @Jason Ross, what's helped this season is (1) we've seen one huge breakout (Hartshorn) and multiple positive developments on the hitting side of things (Kepley, Conrad coming back healthy, Ayers coming out of nowhere as a potential Top 100 prospect, etc.); (2) the pitching depth in this system is *finally* coming around with guys like Wing, McGwire, Kipp, Caple, and Beck all making major progress; and (3) the players who boarded the struggle bus this season have been guys who are blocked or seen as redundant (Triantos, Long, etc.).
Where the system was trending towards a downswing this time last season, the trajectory definitely looks much better now. They're not a Top 10 system, but that also could change if they get someone like Sorrell or Bailey in next week and they start mashing.
