That's not really what I remember. His arm was always a question and his future was destined at 2B barring a breakout in the minors.

Draft profile on MLB.com doesn't exactly scream a SS playing 2B, and his arm grade is also a 50. :

Either way, I definitely agree his D, baserunning, and IQ is definitely not as advertised so far. I would like to see where he's at by the ASB and evaluate from there.
