They need to take a good hard look and determine who is going to be around for the next several years. Anyone who they can't build around for 3-4 years (and rely on!) shouldn't be a part of the plan. Make trades to extend the window.
Players that could be gone after next season: Masa, Story, Conteras, Chapman, Whitlock, Houck, Rutschman, Oviedo
That's a huge turnover that doesn't even include a guy like Duran who people have soured on and Gray who seems like he doesn't want to be here going forward. They need to really figure out what this competitive window is and who should be included. They can't play it by ear year to year. There needs to be a real plan as their prospect pipeline has dried up and they no longer have the assets to deal from. This FO isn't able to successfully manage the FA market! How will they build the next WS team?
