It might be a fit at 3B, if the Crew are able to extend Adames. That would keep Turang at 2B. Only spot on the infield would be 3B. Not sure if he has the arm strength for that perhaps that is what the Brewers FO is trying to understand.
If they don't extend Adames, then in a couple of years Turang will move over to SS and if Black develops might be the 2B.
