Maybe this is a petty concern or simplistic analysis, but in HS when a guy plays everywhere on the diamond it is sometimes because he cannot really play a position. Also, read somewhere that even though bulk/size isn't an ultimate indicator of run production potential in prospects, there seems to be a track record for guys who are Moustakas' size and the track record picking guys his size or smaller this high is scary bad (6' 175-180). It isn't a statistically insignificant population either. I am not a scout or expert on the draft but it was something I read over on baseballprospectus.com.
