Thanks for the edification.
I now have reason to suspect the validity of dWAR.
Shaw is a decent 3rd baseman but he does not have the reflexes , mobility, range, or even arm to be considered a top flight defender.
I watched every game this year and saw almost all the plays that he made. In SpudWAR he is about replacement level or slightly better.
And I like Shaw. He should be the starter in 2017 unless someone else shows up big time.
