1. Screening isn't something I think I have totally nailed yet, so if I lead you astray, somebody will be along shortly to set us straight. But here goes:
The rules are pretty straightforward
- The screener must be set when contact occurs
- If the screener can be seen by the opponent, he can be as close as he wants, short of actually making contact
- It the screener cannot be seen by the opponent, he must give the opponent one normal step before contact
- The screener cannot hold, stick out elbows, knees or hips or otherwise unnaturally delay the opponent.
- If there is no contact, there cannot be a foul no matter what the screener does
- Once he's aware of the presence of the screener, the opponent must go around the screen. Pushing through the screen is a foul on the opponent.
2. The determining factor is where the shooter was when he shot it, not where the defender tipped it.
