I had a felling about that for a long time now. He's loyal to the point where it becomes a bad thing. Rex doesn't know when to cut the cord.
It makes it appear as though he has more loyalty to some player than he does to the most important - WINNING.
I'm not ready to give up on Rex Ryan as the HC yet. If his biggest problem is loyalty to a fault? Then, it should be no problem for Woody to keep Rex around.
I just demand seeing as we go on that he has truly learned from the mistakes that he made with loyalty and Sanchez. WINNING is the only thing that Rex Ryan should be loyal to a fault with.
