A few rules

[lukealex]

I've heard a few rules interpretted differently between officials lately. Here are a few of them, what is the correct interpretation?

1. Over and back: Throw in from near half court, offensive player jumps from frontcourt, catches ball in mid-air, lands in backcourt. Is this over and back?

2. Player is out of bounds without ball. Must player have both feet back in-bounds before touching the ball?

3. Top of backboard, how is the ball determined dead on a missed shot that goes over the backboard, touches the top and comes back into play, etc.

4. Can I player catch his own shot if the shot is an air ball?
