Best case scenario for next year to me is if Riley / Spencer make significant strides (feel decent about Riley doing that, concerned about Spencer), Meadows comes back healthy and performs and somehow adding 2-3 2-WAR position players (would likely have to be through free agency, but trade market with young starters may be possible).
But even with that plus better luck on the starting pitching side? Probably enough to get them back into the high 70s in wins, but hard to see much beyond that. But may put them in a position to compete on 2024.
They really can't do another rebuild, but it's not clear to me that they should or even want to. Between Chris and AJs comments, it seems like they want more to try to build off what they have as opposed to tearing down.
