I think you hit on the key point. All the talent in the world don't mean squat if Brady isn't comfortable throwing to him. I think CJack can get open and his hands have never been in question. But if CJack can't get to the right spot on the field in tune with Brady's mental clock, Brady will almost certainly look elsewhere.
CJack won't prove anything on Thursday since Brady won't be playing much. The interesting part will be seeing if he is running with the 1's or catching passing from O'Connell in the 4th quarter. That will tell us what the coaching staff is thinking. The real test will be in the following 2 weeks when Brady will get most of his work in.
