I think the Padres would keep Tatis, both for optics and because he doesn't make big money in 2024. Soto and Kim both make sense to move. Kim has a mutual option for 2025 which he would likely decline, so I'm assuming he'll be a FA rather than arb eligible (not sure though). He's probably a good target for the Jays who need a 2B and he'll likely cost way less to extend than Bichette, so he can be a Bo replacement for 2026 onwards. Machado and Xander both have contracts that end in like 2045 so I doubt any team is touching those deals.
Preller extending Machado, Cronenworth, and Darvish when he didn't have to, and then signing Xander when he had both Kim and Tatis already on the roster is absolutely a fireable offense. Not sure how he's survived, especially now with the financial issues.
