backcourt

[Ralph Stubenthal]

I'm still confused about certain parts of the backcourt call.
On a throw-in, if the player catches the ball in the air and lands with his first foot in frontcourt and the second foot comes down in backcourt, is this or is this not a backcourt violation?
Also, what if his first foot down lands in backcourt and the second foot touches down in frontcourt and he then steps or dribbles completely into backcourt?
And, what about the 3 point status: the player is not in frontcourt until both feet and the ball are in frontcourt? Does this only aply to a player dribbling from backcourt to frontcourt?
I know you veteran officials are tired of answering questions about backcourt but I promise that if you'll go through this just one more time, I'll probably never ask again, thanks, Ralph.
