This is may be a long shot, but from reading his brief Q&A from the combines, some of the answers to his questions seem to demonstrate a bit of what is known as concrete thinking - which is another way of saying taking things too literally:

Q: What are the five most-played songs in your iPod? What's the one song you hope nobody ever finds out is in your iPod?
A: I don't own an iPod, but I've always wanted one.

Q: When you play Madden, what team do you use? Do you put yourself on the team?
A: I don't play Madden. I don't have a Playstation, but I do want one when I get some money.

Again, I may be reaching here however, concrete thinking is characteristic of schizophrenia - a disease more difficult to treat then anxiety/depression and makes things for our defensive hopeful a lot more difficult to overcome.
