The defensive man shall have the right to be between his man and the basket.
b. On a throw-in which is not touched inbounds, the ball is returned to the original throw-in spot.
c. After a score-field goal or free throw, the latter coming as the result of a personal foul-any player of the team not credited with the score shall put the ball into play from any point out-of-bounds at the endline of the court where the point(s) were scored.
