This stinks, but at a certain level if you weren't bullish on the 2023 team already (raises hand), it's not THAT catastrophic.
As plenty of people on here have pointed out, the window for the team is more likely 2024(25)-2027 and this shouldn't have any real bearing on that. As someone whom didn't think this team had done really anything to dislodge New York, Toronto, Tampa Bay and Baltimore for this season, Story missing time doesn't change the equation all that much. I guess it makes it less likely we beat out Baltimore to be 4th in the division, but beyond that, while MAYBE the 2023 Red Sox looked better than the 2022 Red Sox, they didn't look better than the 2022 (or 2023) Yankees, Blue Jays, Rays or Orioles, with or without a full season from Story.
Get the elbow fixed, and hope that means he's able to play short stop the way he did in Colorado because that gives more flexibility but to the core of the Red Sox and the 2025-27 window, this really doesn't have much bearing.
