O.J. is played out. There's nothing to discuss about him because he wanted to go to jail. His subconscious ordered him to commit more felony so that he'd serve out the sentence he got out of serving a decade ago. He'll acclimate just fine in the big house - with like-minded peers he'll slather them up with football stories of old - he'll be a hero in there.
Don't underestimate the power of the subconscious.
