I've never gotten this straight in my head...I've been on a officiating hiatus for about 8 yrs...coached for awhile...now I'm back to officiating.
#1 Team A is inbounding the ball...A1 throws the ball to A2 who jumps from the frontcourt into the backcourt...violation?
#2 A1 is bringing the ball upcourt and is in the backcourt. A1 passes the ball to A2 who has jumped from the frontcourt, catches the ball in the air and lands in the backcourt...violation?
I've thought it through and thought that in #1 the throw-in isn't completed until the player touches the floor...thus, no possession has been established in the frontcourt. In #2, all three points have not crossed the half-court line (ball and both feet), so no violation here, either.
Thanks for your thoughts.
