A few of the screen scenarios I've seen:

An offensive player sets a screen on the ball handler's defender. When the defender attempts to go around the screener, the screener moves with the defender to impede his movement toward the ball handler. I guess this could be holding, blocking or pushing depending on his action to impede the defender. If the screener turns away from the defender and continues with ball carrier but unintentionally screens the defender then no foul?

What criteria must be met to set a screen behind a defender?

Can two offensive players set a screen on the same defender at the same time?

NF rules: On a free throw, is it a violation to enter the lane before the ball touches the rim or backboard?

Thanks.
