I seriously doubt that Sox will spend additional $100M for 2024.
With the tax payroll limit increase of $4M, accounting for bump in the contractual obligation to Devers ($11.6M), letting Kike ($10M) and Duvall ($7M) go to free agency, and not accounting for other arbitration raises (mainly Verdugo and Pivetta), I only see $50M available. Now the Sox may break the first thresh hold (set at $257M) for additional $20M, I doubt they would go another $20M (set at $277M), bringing the spending increase to $90M.
You are correct about much of payroll burden coming off the books for 2025. We can even alleviate that somewhat by trading away Story if a suitable replacement can be found. We may not be released 100% of his obligation but with Mayer, Yorke and others on the horizon, it maybe something Sox will think about. He's not at 10 year and I don't see a no trade clause in his contract.
It pays to have short term deals and developing young players.
Bloom can target couple of expensive replacements.
