Atkins still made some good moves in 2022 and 2023. The Chapman trade was great and he still made some great FA signings in Gausman & Kikuchi that offseason. The following offseason, Brandon Belt and KK were solid signings.
I think Atkins biggest mistakes were a misjudgment in roster construction. Like for example, the 2021 team lacked a very good bullpen which cost them from making the Playoffs by one game. In 2022, it was awful defense. In 2023, it was the lack of punch in the lineup after going too heavily on defensive minded players. In 2024, it was some poor FA signings (outside of IKF) along with the weak farm system being exposed when they lost a lot of BP arms or other players to injuries.
Atkins has been so/so during his tenure here. He's done some things very well but has also done some things very poorly. It's been mediocre overall, which is a fair assessment.
