It can be easy to forget now, after three straight successful seasons, but when the Chicago Cubs originally signed Cody Bellinger, they were trying to resurrect an MVP's career.
Thanks to a litany of injuries suffered with the Dodgers after his legendary 2019 campaign, Bellinger simply lost his ability to perform like a star around the time of the pandemic. His 47 wRC+ in 2021 was awful, and his encore in 2022 (83 wRC+) earned him a one-way ticket out of Los Angeles.
Thus, the Cubs signed him, and they succeeded in reviving his stardom.
