This is pretty close to what I've been saying (too often).
JH has reacted strongly to all the stupid acquisitions, including some (Price and Sale) made by DD.
The 2019 Sox roster had most of the terrific players from the 2018 best Sox team ever and the highest payroll in MLB. But, because of the collapse of the pitching--the 2019 Sox were ranked 19th in MLB in team ERA--they didn't make the playoffs.
Even worse, if the Sox wanted to stay competitive, they would have to spend a lot more than the highest payroll in MLB. Mookie was a free agent and eager to get major dollars, which the Dodgers were happy to give him. Sale and Price, getting big bucks for being worthless on the mound, needed to be replaced with two more high-price arms. And so on.
Enter Chaim Bloom, apparently with restrictions on what he could spend on pitchers. Specifically, no long term big buck contracts which have become almost the norm for the best starters. Inevitably, I think, CB was fired.
Enter Breslow with, I believe, similar guidance to that given to CB: no big contracts for starters. Plus I am almost certain the Sox brain trust, probably with input from JH himself, was more than happy to make the Sale deal with the Braves, including paying them $17M this season when Sale has re-emerged as the old Sale. Thus too the $38M for 2 years of Giolito, 1 year of which is already shot.
Thus the humungous irony of this 2024 season in which the Sox rotation is the best in a long time. The Sox team ERA if 5th best in MLB over halfway into the season. And their aggregate salaries (for Houck, Crawford, Pivetta, Bello, Criswell, and Winck) are less than the $16M closer Jansen is being paid!!!
One more time. Without Sale and without Giolito, the Sox pitching is vastly improved from last year and even better than the 2018 team ERA, 3.75, ranked 8th. That year Price was paid $30M, Porcello $21M, Sale $12M, and Pomeranz $9M.
And let's not forget that before the semi-disaster of the 2019 season, JH was more than willing to pay big bucks for all kinds of players, not just pitchers. Remember the disaster of the 2012 season? Sox payroll was 3d highest in MLB.
JH is easily the best owner the Sox have ever had, but there can be no question he has relied on his brain trusts over the years. They not only brought 4 WS (after 86 barren seasons), but the best Sox team ever, 2018. I think in 2019 he just got tired of shelling out big bucks for players who failed badly. Don't forget that early on he hired Bill James, the author of sabermetrics and a believer that you don't need a massive payroll to produce a winning team.
