First play that Warner illustrated.... it makes sense if the QB can diagnose the coverage at snap. Niners were giving a zone look even with the motion. The CB does run up to press, but Niners still have a tendency to run Zone. Maybe the quick feedback is that Goff should have checked the top side first. Just a quick glance.. vs keying in on the near side all the way through. Peace on that.
I like these analyses, but at the same time, these can be very skewed to the negative side which may give the "wrong" overall impression of QB talent.
A QB is not going to be 100% perfect in the game. What would be 10 times more helpful is Jared broke down what he saw. Unfortunately, we don't have that.
