It isn't just the pitching pipeline...
This team has had Jonah Bride, Kody Clemens, and DaShawn Kiersey on the big league roster for much of the season. Julien and Miranda may not make it back to the majors. Wallner looks like he's headed down the same path as those two guys.
Overall, this has been a systemic failure in terms of drafting, player development, roster building, etc..
In some respects, Falvey's done a better job with the pitching than he has the position players and that is absolutely terrifying.
