Hi Everyone,
This are NCAA Men's Questions
Q1- When exactly does the center line re- appear during a throw-in? When a player touches the ball, catches the ball in the air , with one foot on the ground , two feet on the ground etc etc ???

Q2- During a throw-in A1 jumps from his front court and receives the ball while in the air. He then lands with his first foot in the front court and his second foot in the the back court. Is this over and back?

Q3- A1 dribbles up his back court and picks up his dribble while straddling the center line. He then throws a bounce pass- the ball actually bounces on the floor in the front court to A2, who is also straddling the center line. When A2 receives the ball while straddling the line should over and back be called?

Our Association , which has recently reverted from FIBA to NCAA rules is really divided on this area and we would appreciate a definitive answer from those who are more experienced in these rules.

The line "re-appears" when the person who catches the ball has two feet on the ground or when the person to catch it passes the ball (which ever occurs first). The exception only applies to the first player to catch the ball.

For example: If A1, having jumped from the frontcourt, catches the ball while in the air and then, before landing, passes the ball to A2, who is in the backcourt, it is a violation.
Legal play. The player is allow to make a "normal" landing even if the first foot down is in the front ourt.
Yes. While in A1's hands, the ball had backcourt status. On the pass, it obtained frontcourt status when it bounced in the frontcourt. When A2 touches the ball, it once again obtained backcourt status. Violation.

Hi Cameron
Thanks for your prompt reply.
Next Question: On the bounce pass from player A1 straddling the line to player A2 straddling the line.
What is the status of the 10 second count if the ball bounces on the front court?
Pistol

The 10 second count ends when a passed ball touches the floor in the frontcourt. The ball has frontcourt status at that point.

Get ready to blow the whistle for a backcourt violation as soon as A2 touches the ball.
