Turang could be one of those scenarios (like Adames) where we hold him to the very end, have (hopefully) four more playoff runs with him, and then take the pick...
That said, as you just mentioned, beyond Chourio, we don't have other long-term contracts... in a couple years Yelich falls off... if Made/Pratt are starting to make an impact at the big league level (hopefully we can figure out 1B), and our pitching is starting to gel for a "go for it" type stretch, it will likely be ideal to keep some stability in place with Turang, Frelick, etc... So even if we're paying Turang $25/per and Frelick $15/per, with some of the younger players locked up (Jackson, Pratt, maybe Made) things could work out...
3-4 years down the line, our pitchers (if they pan out) will start hitting Arby (Miz, Patrick, Priester, Harrison), so that might make 2028-2031 or so our "window", before we re-load again
