Justin Turner - position?

I was just looking through the M roster and I read Justin Turner's mgoblue profile.  It's amazing how universally regarded he was at one or the other DB spot.  Based on our defensive backfield this fall, I feel like we need to get him on the field. 

What is this based on?  Not sure.  It seems as though the reports on him go back and forth between "he's such a talent who will see the field somehow" to "he's just not picking it up like we thought  he would" to "he's kind of a tweener so we don't know where to play him." 

Here's what we know about him:  He's pretty big for a DB, 6'2" and 200lbs.  To me, that sounds like a safety.  However, he was rated by Rivals as the third fastest DB nationally, and those spots are reserved for the guys who are unequivocally fast.  So maybe that means he can be a CB.  Either way, he's a physical freak who has produced at a high level in high school and impressed at the AAA game.  Don't we need to get him on the field?

We have 5 DB spots.  The only one we know for sure is Woolfolk, likely at CB.  But out of the other 4, where does Turner fit the best?  My suggestion is one of the spur/bandit spots.  It sounds like Vlad or CG will man the FS, and I think between Cullen, Floyd and Rogers we will find a second CB.  But the candidates for the spur and bandit are a walk-on, a bunch of guys who've also never seen the field, and true frosh.  Let me know what everyone thinks, or if you've heard anything about this that I don't know, let me know.
