To be fair, we’ve seen plenty of cases where old/bad teams bounce back and have a great season the next year.
Happens fairly often with the Redsox, Yankees, Giants recently, San Diego more recently, etc.
However “hope” isn’t exactly a great strategy to employ. Although it looks like they’re deciding to run things back once again, so really all we have is hope. Unless they can somehow manage a savvy retool similar to the Padres.
