If you watched Kaepernicks body language during the game and the post game presser, he was flat out defeated.
People used to bitch about Hass being "mentally fragile" which he NEVER EVER was, but that was the term that came to mind watching Kaepernick.
In the post game presser, it seriously looked like he had tears in his eyes, his head was hung in defeat, he didn't want to make any eye contact with reporters, and he was making a few seemingly smartass remarks.
I think it's very well possible we got in his head, and I've always thought that benching Smith was a joke, and a bad move.
I noticed that in the game as well. He was sitting on the bench looking dejected and sullen. Not that he should be artificially pumping himself up, but he should at least be engaged, talking with his coaches, talking with his receivers, or something.
