By "bust" I'm assuming you mean he won't be a starter at either tackle or guard on either side of the line.  If that's the case, I disagree, the ability he's shown to (successfully) line up at any position shows he has the mental capacity not only to play those positions, but an aptitude to understand the entire OL scheme.  Add his athletic talent, his ability for counter-moves, and his ability to deliver a strong OL punch and I think he's easily going to find a spot.  As I said above, he may not be a top 5 LT but I think he'll deliver a solid performance on the OL (RT would be my best guess.)
