Trading Smith and Rosario didn't help, but, it seems like the Cubs draft well enough and have enough high ceiling types in the lower levels that they (ideally) should be able to fill those holes out by the end of 2025 while still having a robust top and bottom third of the system.
I'm willing to take Longenhagen's POV with a grain of salt, but oof, that list really drove home the point that the Cubs have issues when it comes to developing high end pitching prospects. Yeah, yeah, I know, TINSTAAPP, but Horton was the only one on that list whom Longenhagen thought had a realistic shot at being more than a back end of the rotation type, and even that was couched with serious injury concerns.
