Casty, unlike, last year wasn't actually good, but he got a few hits and drove in three of the four runs the Phillies scored in Games 2 and 4. Good for him, but obviously not a formula for offensive success either. No question the loss of Bader hurt - the defense, the downgrade to Nick, having to play Marsh against LHP.
For sure about being patient with rookies PC. Marsh (with the Angels) and Bohm and Stott all went back to AAA the first time. If they keep Bader and lose Nick (or even if they don't lose Nick) a Crawford/Marsh/Bader OF is still lacking the same thing it always has (except when Nick was hitting), and that the roster has since '22 (when Nick also wasn't hitting but we had Rhys).
If you really run it back (including Bader) you probably do want to double down on pitching and bring back Ranger. But I think I'd sooner extend Luzardo. Locking up Ranger from ages 32-35 seems risky with Nola already a similar risk (and Walker also demonstrating the age curve, even if he had less far to fall).
