Not enough to get him.
I can't see any rental I'd trade a top prospect for.
Looking at the soxprospects.com top 20 and next winter's Rule 5 players, I'm not sure all these guys can be part of the 2022 40 man roster or extended future with the Sox.
I'd form 3 groups on how I view who I'd maybe trade:
Nope:
Casas, Duran, Downs, Jimenez, Houck, Bello
I doubt it:
Seabold, A Ramirez, Yorke, Mata, Song, Winckowski
Maybe:
Groome, Bonaci, Jordan, Murphy, Lugo, F Valdez, Wong, Ward
