Impossible to know since they traded him about 8 months before the pandemic hit. If we assume they don't trade him and the pandemic still hits, I think it comes down to whether he was all about trying free agency or whether he just wanted to be paid like one of the top players in the game. Everyone keeps saying he was committed to free agency, but I don't buy that since he and his agent made a counteroffer to the Red Sox when they made their 10/$300M (or whatever it was) pitch. If you're committed to going to free agency, you don't give a counteroffer unless it's so beyond ludicrous that it would be obvious as nothing more than just a ploy. Some might argue asking for $420 million over 10 years was one of those offers and maybe they're right, but the Red Sox should have split the different and offered him $360 million over 10 years (assuming they didn't do something like that) and see what the response would be. They made that offer, reportedly, knowing they were over the luxury tax even if he didn't ask for more, so clearly they were prepared to go over again if need be to keep him, but must have concluded that a gulf of 10 years of an extra $12 million AAV was a bridge too far and pivoted back to trying to get under the tax by dealing him away.
Either way, this belief that Mookie was going to free agency no matter what is, I still believe, a bit of a misnomer, as is the notion that the Red Sox were not willing to deviate from the plan of going under the tax threshold. Any way you slice it, regardless of who thought it was a good idea at the time, the Sale contract clearly was a limiting factor in future negotiations.
And even if it had ZERO bearing on the Mookie stuff (which is a specious theory, at best), it's still looking like one of the worst deals ever handed out since he hasn't even thrown a pitch since the extension officially started and we are already wondering/hoping he comes back as good or at least close to as good as he was before. It's been two calendar years, roughly, since his elbow issues first started flaring up and he's been Jekyll and Hyde, usually the latter, since striking out Machado to end the World Series. People are right to still kvetch about it in relation to this topic because, regardless of what is fact and what is supposition and what is outright falsehood, they will always be inextricably tied in the eyes of Sox fans.
