My prediction is Profar to play a few places but mainly second. Kim is also possible to play mainly second. Arenado would be good, and is certainly possible too. It might be Casas for him and I don't love that. We shall see what happens.
Btw, I do not mind moving Casas because he absolutely loves himself. Sometimes you have to make a personality/chemistry trade despite the player having talent. Slightly before my time, but Reggie Smith was said to be an example of this. Arguably,Nomar was too but defense and injury were also factors.
