Ironically, in Brady's 2nd year (9-7, no playoffs), he did the same thing. He'd get that downtrodden look and sit on the sideline with his head down. He said his father told him he affected the whole team when he acted that way. He worked on it and turned it around, obviously. So, if this is the case with Sanchez, it certainly isn't something he can't overcome. Just another stumbling block in the road, he is a young QB.
