There will be no need for accurate footwork timing because you will have to either plant your foot forward or back (which almost every real cricketer do in real life)
IF Neutral=back-foot,but still you need to move the LS down for the foot movement of the batsman based on line and length of the ball. For example :the ball is pitching good length around 5th stump,without footwork how would you move the batsman to reach the ball without LS movement.
