I was following this story this past summer and as I recall there were several layers to this onion....the Diamondbacks front office was giving him the cold shoulder BEFORE his medical examination which to me implies they were having second thoughts. Apparently there was some disagreement in the front office of the Diamondbacks as to who they should draft and when/if they should take Loux (the GM that drafted him was later fired) and Barret Loux got caught in the middle....read this article from this summer for more information.

"Loux was expected to be a late first-round or second-round pick going into the draft. According to FoxSports.com's Tracy Ringolsby, then-Diamondbacks general manager Josh Byrnes and then-professional scouting director DiPoto overruled scouting director Tom Allison and his staff's desired choice and selected Loux with the team's first pick. Byrnes was fired July 1. DiPoto is now the team's interim general manager."
