If Story can't really hit, I don't see another team wanting to trade for him. Mayer is good at SS, but not as good as Story right now. I think they are ultimately stuck with Story unless they are going to eat a lot of his salary. I don't know how willing Henry will be to do that. With Sale, it was for just one year. Also, Story has an opt out after 2025 which hurts his trade value to any other team that actually wants him around for a few years.
The best problem to have is Devers playing a solid 3b, Story hitting well, Grissom finding his feet at 2b and Mayer making a lot of noise in MiLB.
