I disagree with this. The defense this year wasn't good enough to be put into vulnerable positions from a "gunslinger" QB. That's why JR was the better choice for this team. He made the safer choices. Now let me also say this offense needed to take more vertical shots; which CJ is better at. Its his decisions on the other plays that keep him from playing more.
So you're pretty much saying a qb who scores on a very low percentage of drives is better for the team than a qb who scores on a high percentage of drives because of the possibility that he will throw interceptions that he proved to rarely throw?
As far as the defense goes. Their biggest problem this year was giving up big plays. When you give up big plays, your opponents starting field position doesn't matter.
