Please increase AI defense positioning

The defense is not expanding and contracting.  They hold formation like robots.  The CB's spread so far apart from each other and don't work in tandem when controlled by the user.  The AI is extremely cohesive and intelligent when it works together with other cpu controlled players but when the user controls the defender and attacks the cpu controlled support defenders do not interact cohesively and intuitively and intelligently and they actually will run away from assisting unless you hold the RB button which is just counter productive and literally causes your own teammates to work against you and run into you and almost act like extra defenders.
