I'd like to also not have a garbage bench next year.
Yes, Bregman, Hoerner, and Swanson are all signed for the next four years. But in that four years there is a high chance that at least one of them misses significant time with an IL injury (strain/sprain), a non-zero chance one of them misses more than half a season with an injury requiring surgery or breaking a bone via HBP. There is a high chance one of them will have a nagging injury like Nico's injury that required surgery following the 2024 season.
If that happens do you want Shaw manning 2b-3b for 20-60 games or Nick Madrigal.
If that doesn't happen, in 2016 Ben Zobrist had 631 PAs, Addison Russell had 598, Kris Bryant had 699, and Javier Baez had 450.
This is not a problem that needs solving.
