What am I assuming? Other than the comment about height, I qualified every statement I made. You are assuming Sano's size equals less agility. You don't know that. I addressed your concerns about Sano bulking up and his agility which is finely tuned mobility. I would tend to agree NBA players couldn't play 3b because, well, they are trained to play basketball not Major League 3b(I've never liked comparing sports, difficult to defend and/or refute). Again though, that's an assumption. As for his fielding, he may be bad now but when was the last time a polished 19 year old infielder broke into the majors? The last two position players I can remember are Andruw Jones and Bryce Harper, both outfielders. I just think it's too early to be having this discussion with regards to Sano. He is at least a full year away and likely more.
