We can agree to disagree on where the respective teams were starting from, I suppose. I mean, technically the Red Sox line up in 2004 was pretty much running it back from 2003 (Walker to Bellhorn, of course). Same for 2017 to 2018 (at least in terms of young players - though they did add an "old DH" that couldn't play the field). I suppose a better way to say it is, I really don't think the Red Sox line up is all that good. (Again, if you're only scoring the 9th most runs and you have the 2nd best hitters park, I don't think that's good enough IF you're going to have terrible infield defense as well).Teams get better performances due to better health luck and improvement in players that aren't under 25 all the time. The 2023 Rangers must have been stupid to expect a different result when they ran back the same lineup that won 68 games in 2022. Then they won 90 games and the World Series with the only under 25 addition being Josh Jung. The Red Sox have a lot of talent already on the roster and running it back has just as good a chance of succeeding as bringing in the different flawed players who are available now.
I think it'd be "good enough" if they fixed the infield defense, for the record. I also think it'd be "good enough" if they had acquired JD Martinez v2025 - and who knows, they still might! But, I don't believe in Story enough to say that Story and Campbell/Grissom/Hamilton will fix the infield defense. Something needs to be fixed. They either need to score a lot more runs or prevent them. I don't think they're going to score a lot more runs. Crochet will help in the "prevention" department, but only so much.
