Ai pursuit/reaction time logic

The way ai reacts to change of direction is completely wrong and unrealistic 

a successful juke shouldn’t be dependent on getting an falling/faked out animation

If a ball carrier cuts to the opposite  direction than the defender and the defender has not changed direction aswell,the chances of him tackling the ball carrier should drop to like almost zero 

Theres been countless times when i cut back on a defender and they’re not even facing me and  it stops my player to play an animation  that snaps them infront of me so they can make the tackle

My player should not be restrained from moving unless i am wrapped up or knocked off balance
