I think Raffy is the 3B unless they bring someone else in. They don't have anyone in the org right now who can be a 3B for 162. Could Dalbec sub for Raffy here and there, probably. I think if the left side of the IF was Xander and Dalbec, the defense would look really bad.
Casas is a shoe in to be the 1B at some point in 2022.
If Xander isn't traded, the question marks will be 4th OF/2B/C. Are they comfortable with Duran as the backup? Can Arroyo stay healthy? Bring back Iggy to compete for the starting role and provide backup at SS and 3B? Do they want to spend 7M on Vaz? Cut bait with Plawecki? Will they try to rotate Wong in?
