Bo may have just tinkered with his swing too damn much. Looking at his spray chart, he started with most of the hits (and hrs) to the pull side, then 2021/2022 peak years he was using the whole field. 2023 and even more so in 2024 he's primarily hitting oppo. Maybe he tried to start his swing later, give himself more time to see the pitch before committing (and cut the K's). Whatever the changes, it's f***ed him up.
