Clarifications sought: Verticality, Reaching in , High Dribble--anybody help ?

[Travelling Man]

1. A "high dribble" is NOT carrying the ball. But rotating the wrist by dribbler is carrying. When a player is speeding down court and dribbling the ball and it bounces above his waist or shoulder but no wrist pronation on dribble is this legal? Coaches and fans are always screaming 'violation' when they see this, but is it really a violation?

2. "Reaching in" --if the defender does not make contact with hand or arm of opponent and does not impede their progress, then they can reach in all day long and make the dribbler cautious and slower---is this just smart defense?

3. "over the back" is not the same as "on the back". Verticality is legal-on a rebound the player jumps high and veritcal and grabs rebound--no contact is made on the back of other player. legal rebounding and congratulate player on having a good vertical jump that is well-timed yes?

4. "shooter shoots, ball gets stuck wedged betw. rim and backboard"--so team A has put the ball out of play. why doesn't possesion go to team B?
