I have Moustakas as my 18th 3B option. I think people will expect a large jump in his production this year, and his flyball, K% and lack of walks is not the profile of a player that is going to take a huge step forward after going .242/.299/.412 over a full season of AB's.
I have him at 18 hr, .252 BA, less than ideal counting stats.
Back end CI option, but I'd much rather grab Seager who might not even reach his homer total from last year in 2013, but should improve in BA some also. I think I'd even roster Youk before Moustakas as a deep league CI option.
