I don't disagree that different scenarios could play out and the FO needs to be ready to handle each and every one of them.
I just prefer to plan on success except when in a rebuild phase. Trade value at the deadline means little to me during off-season planning. If the team tanks but certain pieces like Paddack were productive, by all means, pivot and sell him (and other expiring contracts, etc). A good FO can do that on nearly a moment's notice, based on whatever standard talent evaluation methods they have. It's a tactic, not a guiding strategy.
What I wrote in response to DJL44 was basically that if Paddack is going well then the team has a higher chance of going well too, and if the team is in sell mode at the deadline then the odds are higher that Paddack has flamed out again. Not that he is key to the rotation, but I still see only a thin sliver of scenarios where he's trade bait. However, for off-season planning purposes it's fair to at least acknowledge that in such a scenario, his contract is modest enough that he's not certain to be untradable - he's not Kyle Farmer, where even the player himself expressed surprise he was kept at the price he cost.
I don't like trading away pitching. But if there's a reasonable chance that other in-house options will perform as well as the unpredictable Paddack, I might trade him simply because his is an expiring contract going into 2025. If he fails, he fails. If he does well, it's only for a season and that's not part of building a sustainable winner. Only if 2025 is a go-for-it year and Paddack is a key to that effort would I feel differently IOW he's not Sonny Gray, either.
