It's the order of the deals.
I didn't really look at it as a classic 3 team deal because the deal as initially shown made it seem like the Red Sox aren't trading anything to the Twins. Now, it reads as if it's two separate deals (Betts & Price for Verdugo & Maeda, followed by Maeda for Graterol), and the first trade is gross incompetence because there's no reason they should have been interested in Maeda even from a value standpoint. I assumed the Red Sox went to the Dodgers, said they wanted a starting pitcher prospect, and then the Dodgers went and found one, since they didn't want to trade any of theirs. The idea was that the Red Sox weren't dealing with the Twins at all and they shouldn't have.
The trade benefits the Dodgers the most, so the fact that the Twins pitcher is insufficient shouldn't mean the Twins have to do anything now, and they'd have no interest because it's not like Maeda is great or anything. They thought they paid full value for him. It should be all about the Dodgers making up the difference.
To me, the order of the deals and what Bloom values is important, and I have a different view of him if he thinks that he should be working with the Twins versus the Dodgers on fixing the deal.
