Next year is always a year away. If the target year is 2024, then they will need to start building to that this offseason. They won't build everything in one off-season.
That said, I agree completely on not trading away key prospects for short-term vets. But if they sign a few guys with a few years of control, trade for another Grey (Shed who?), and maybe even pick the prospect the like least to do another Bauer-type deal, that would not just be for next year, but the year after.
