Yeah but there is no way Trea Turner is not the Phillies shortstop next season, and probably the season after that as well. The season he had defensively this year ends that conversation about moving him for now.
If you're content to keep Miller in AAA all of next year (and not trade him) you can cross that bridge in December, but if he's ready to play in MLB at some point next year it won't be at SS, unless it's as an injury replacement. And he should probably get some reps at 3B in AAA next year. And we know the Phillies will be open to moving on from Bohm.
Gelb suggested Bohm is better 4th, and perhap JT 2nd. I like Bohm well enough #2 though unless Schwarber has already driven himself in it's a formula for double-plays as well.
