And as I said, I'm not discounting your opinion. It's simply as I see it there are coaches who know how to coach up QB's and those who don't. Certainly every coaching staff in the NFL tries to stop the QB's they draft from turning the ball over. They all try to teach them proper footwork and not to run into sacks among many other things. My assertion is simply that some coaches have the ability to accomplish those goals and some coaches don't. That's one of a multitude of reasons why great NFL HC's are so few and far between.
