I need help verifying that I am right. Player A brings the ball up the court and crosses the half court line. Player B is following behind and jumps over the halfcourt line from the backcourt while Player A is passing Player B the ball. If Player B catches the ball in the air before ever landing in the frontcourt, would it be a backcourt violation?

Yes, assuming that A is dribbling across and has all three points (both feet and ball) in the front court.

BITS,

Doesn't A's dribble end when he attempts a pass, and if so it should not matter whether his second foot is in the front court. In other works as soon as A attempts the pass, and ends his dribble, if he picks up his backcourt foot, with his pivot in the front court, he then establishes front court status.

Is that clear as mud?

Darn this cold medicine :) Yep. Once he ends his dribble, the three points rule no longer applies. If he's touching frontcourt, and not touching backcourt, he's in frontcourt.

First, Welcome. Second, keep in mind when posting A refers to offense; B is defense. In your post, most will say that it is not a violation because player a (offense) passed the ball to b who is (defense).

I think you was trying to say that player A-1; passed the ball to player A-2 who jump from BC to FC. You have to look at rule 4-35. You have three criteria that must be met.

art 1... The location of a player or nonplayer is determined by where the player is touching the floor as far as being:
a inbounds or OOB
b in FC OR BC
c outside or inside the 3 point line

art 3... The location of an airborne player with reference to the three factors of art 1 is the same as at the time such player was last in contact with the floor or an extension of the floor.

So if A-1 is passing to A-2 A-2 jumps from BC to FC and receives the ball while airborne then you have a violation.

I think it's pretty clear, but it points to a very difficult to read moment.

The 3-points (2 feet and the ball on the dribble) rule can be applied nicely if all we're concerned with is the dribbler possibly violating - solo. Did he or she make it into the front court yet? Then bounce the ball on the line? Violation.

You are pointing out - if I understand you correctly - that a dribbler might, for example, end a dribble by picking the ball up while on his/her front foot which happens to be in the frontcourt. In that case, the 3-points rule no longer applies, the player is in the frontcourt, and passing the ball to a teammate with backcourt location would be a violation.
