The Great News: The rotation. I was extremely skeptical early in the season regarding the Cubs' rotation after 2023, but, Steele, Assad, and Wicks all stepped up in huge ways, and Stroman's first half was excellent. If Taillon doesn't actively crap himself every other game next year, and Stro opts in, this could be the best 1-5 in baseball (assuming health) next year. There's also depth in the system for the first time in forever.
The Good: The offense stepped up. There's a good core here, even without Belli. There's room for improvement, and they were subject to some really annoying slumps, but I think they just need one solid bat instead of the five I thought they needed coming into 2023.
The Mediocre: Coaching and management. I'm not convinced Ross is the guy to lead this team back to the promised land, but credit where it's due for the development of the pitching staff.
The Bad: The fail rate of certain high level hitting prospects coming into the season. PCA, Canario, and Mervis all fell on their faces in the majors, be it because of development/usage or otherwise. Brennen Davis got hurt again and hasn't looked the same. There have been other guys who took steps forward in High A/AA, but Amaya and Morel look like the only guys with a guaranteed spot on the 2024 Opening Day roster.
The Ugly: The bullpen. Aside from Alzolay, the pen needs a complete gut rehab this offseason.
