There is 'on the list' and 'off the list'
If we are just going by the top-50 MLBR list, my choices, in no particular order:
Okamoto
Kim
Imai, maybe
On the off-list, and these are like a roto wish-list:
Green, Burns, Chandler, Alcantara, Lodolo
Marte
I'd also throw in Bregman on the off chance that he could be talked into a long-term, cheap AAV because he wants 6 years in Fenway to enhance his HOF credentials.
