How can you do that if you're not used to passing on normal plays?
I am not exactly sure what you mean by that, because we pass on a lot of normal plays. Its the runs that are weird.
Cam's accuracy on medium and long throws seems to be just as good as it was last year. He was throwing strikes on anything longer than 10-15 yards the last couple of games, so the read option doesn't seem to be impacting his play in that regard. Most of his recent mistakes have come on the short stuff, and imo thats more of a concentration/focus problem than anything. And that is why I think it will get better with age and experience.
Now there are some times when he holds on to the ball to long, and that could be lack of experience. Or it could be the plays, or that receivers are not getting open, or some combination of the three.
