What is more likely is that Soto signs with a NY team and Boston immediately overpays for Fried.
That would be a horrible move if -- and I'm sure Brez and Co. know this -- the Sox don't improve the infield defense. So the corresponding dominoes will be signing a third baseman, and trading Casas for pitching.
If they also lose out on Fried, expect another overpay for Burnes, a reliever, and Teoscar... and Devers stays at third for another year.
In either scenario, eating Yoshida's contract and trading Abreu for more pitching (and to make room for Anthony) are also likely.
I don't expect Brez to also sign a #2, as they will also be overpays, if Kikuchi's contract is any portent. They will try to add another starter in a trade. Any leftover budget will be spent on more relievers and a back-up catcher.
