Reportedly another team approached Bloom about taking Sale's deal in July of 2022, but they didn't want to trade back anything worthwhile, so Bloom rejected the deal.
And that was before the bike accident. Flash forward through a 60 day IL trip for shoulder inflammation in 2023, and Atltanta still wants to gamble on Sale, and maybe will give up a decent player. But that means in no way do they pay full freight. Breslow asks for a player he likes (Grissom) ad pays down the amount. Then it just comes down to Atlanta appeasing Sale so he approves the trade, and the Sox replacing quality with durability. (Clearly even Sale lacked confidence in his durability. He pushed back free agency by two years and even overwrote a more lucrative option year. Those don't sound like the actions of a guy who knows he is back 100%.)
