You telling me Andrus couldn't play third as well as Moncada can? Honestly I don't know where Moncada should be playing. And this past situation at second base, nothing says Moncada simply improved in the field in general since that small sample size snapshot in his career, and could play second base passably, where his occasional power would make him even more valuable. Sacrificing power at the altar of defense for third basemen is not a widespread model for sure. It would be very easy to replicate. Team don't do that for a reason. Power is that reason
