You are right as always, Batman (woman). Trading T.J. at this time would be totally moronic. Good safeties are hard to find and T.J. is a good one. T.J. has great versatility in the back end and as a LB in the box - yeah, I know Justin Carter looks good there right now in preseason games, but he is nowhere near ready. 

The NFZ is wonderfully cohesive; why mess with it. Let T.J. play out his contract.
