in/out of bounds

[betweenthelines]

1st.. A1's team has ball.. B1 is screened on the end line. To avoid the screen, B1 steps out of bounds then re-enters the court. Is a technical called on B? NO........B1 WAS FORCED OUT OF BOUNDS BY THE SCREEN.........THINK ADAVTAGE/DISADVANTAGE IN THIS SITUATION.BY SETTING THE SCREEN AND FORCING B1 OUT OF BOUNDS A1 GAINED A HUGE ADVATAGE.NOW ON TOP OF THAT WE ARE GOING TO DOUBLE PENALIZE THE DEFENSE WITH A "T"

2nd.. A1 has ball and B1 is defending. While driving upcourt, along the sideline, A1 and B1 have incidental contact, the ball is momentarily loose (in-bounds), A1 steps out of bounds, re-enters and re-gains possession of the ball..LEGAL....A1 CAN GO OUT OF BOUNDS AND THEN COME BACK IN A GET THE BALL; HOWEVER, IF A1 DRIBBLES THE BALL, AFTER HE COMES BACK INBOUNDS, IT IS NOW A DRIBBLE VIOLATION DUE TO THE FACT THAT WHEN THE INCIDENTAL CONTACT OCCURED HE HAD BEEN DRIBBILING THE BALL.
