'23 AL averages per 600 PA: 19 HR 69 RBI .247 BA .317 OBP/.411 Slug/.728 OPS
Without pro-rating every guy on the roster (the Sox had three with 600 PA), there were four with at least 19 HRs, three with 69 RBI, but seven who hit .247 or better, and got on base and had a higher-than-average OPS... the skillfull seven: Casas, Devers, Duvall, Duran, Turner, Yoshida, Verdugo.
The first five had at least .800 OPS, including three who qualified: Casas, Devers and Turner. The first two guys can certainly improve, and hopefully, so can Masa. JT is probably a goner, and may not be replaced from outside the org -- if the bulk of spending is appropriately on pitching.
Moon asked if a few new studs at the top of the rotation, added to most of the returning roster, is enough to win. Depends on... winning what? Another handful of games to nab a wild card? Maybe... depending on the progress of younger players. Improving the pitching of a last-place loser more than likely makes them an average team.
Enough to win it all? Very doubtful, unless you're assuming Martin and Jansen at a year closer to 40 will not regress nor get injured, and automatically repeat their '23 successes.
