I'm not sure if this is an indictment on Kaepernick or the Niners offensive coaching staff. On one hand, doesn't matter what the play is if you are the QB you need to read the entire defense and account for everyone. No excuse whatsoever for an NFL QB to miss that. On the other hand it tells me that Kaep probably didn't have any sort of pass option to check into on this playcall which is why he wasn't even bothering to look over there. What would have happened if StL put all 11 guys in the box, would Kaep have had to call a timeout since the only play-call(s) were runs? I would say that it would have been an easy TD since Torrey Smith was probably the fastest guy on the field, but really Kaep probably throws the ball 10 yards over his head anyways.
I said that this team has 8 win talent so anything over/under that would tell us a lot about this coaching staff. Well looking at the schedule right now at this point it is very tough to imagine them getting beyond 4 wins and so far the only coach showing any signs of having any sort of competence is Mangini.
