Absolutely. I just personally don't see it a blunder not resigning a guy like Schwarber, Erod, or Turner.
No one ever says the Sox lost Cody Ross to Arizona or Scott Atchison to NYM, but they also went out and got Shane Victorino and Koji Uehara and won a world series the next year.
Players are replaceable, with the exception of guys like Betts.....who are much much harder to replace. But finding a Schwarber or an Erod is not very hard at all. Sox just don't want to invest in those guys and the guys they have invested in to replace them have largely been lackluster.
If Kluber came in here and pitched like he had something left in the tank, Whitlock stayed healthy and pitched well, Jeter Down panned out and took over SS, and Yoshida was better on defense and didn't tail off at the of the year with the bat how much better might the 2023 team looked?
Sox made all the right moves, in terms of trying to fill holes, they just made the WRONG right moves. Is that cheapness? faulty player evaluation? bad coaching? or just bad luck? Probably all 4, but when you can consistently do a few of those things right you can cover up for a bad signing here and there, a bad trade, a bad draft etc etc etc.
The only bright spot today compared to 4 years ago is the farm is better, and honestly, 3/4 last place finishes and no real big trades in a long time should render a better farm system than just middle of the pack.
Sox have a lot of work to do.
