For me the defender lines him up and never even acts like playing the ball. As I've said in midfield or on the wing if a defender does that has a guy knocks the ball past him it is being given whether the player dribbling is running fast or not. But in the box the rules are always different.
Same goes for that Turkey handball the other day. If it is the center of the field and a guy flicks a ball past a defender whose arm is out like that and blocks it the handball is being called. That's just how it goes.
Your understanding of football really confuses me.
