That's basically it. He wasn't supposed to spend much, and Mookie was rather pricey. And outside of Devers, he really did not.
Story and Yoshida were expensive, but these were not upper echelon contracts. And Yoshida was signed in an offseason where 8-12 year deals were being handed out like Halloween candy, and his deal was still only 5 years. Although it will seem longer if he doesn't get hit hitting together.
The Sox are still spending near the middle of the pack, but that number will probably drop precipitously. After this year, the only deals on the books with an AAV higher than $6mill will be Devers, Story, Yoshida and Giolito (assuming he does not opt out, which is a very, very unlikely event). And the only players eligible for arbitration after this year are Joely Rodriguez and Reese McGuire. I expect (hope) Rodriguez will be non-tendered, and there is a non-zero chance McGuire is as well, assuming he is not simply traded...
