Back court?

[kbilla]

Every year I need to refresh on this one. A1 inbounds from sideline to A2 who jumps from A's frontcourt to A's backcourt, catching the ball in the air and landing completely in A's backcourt. Backcourt violation? I believe it is under the whole "position of ball on court" theory that the ball has the same position on the floor as a player who is holding it - in this case the airborne player is considered frontcourt when catching the ball and then lands backcourt. I have had people tell me that it isn't though b/c the ball does not have any "position" on the floor until it is possessed by a player on the floor...not sure where this comes from if it is the case...

Same story except when A2 alights (great word), he/she has one toe on center court line before jumping in the air. Backcourt violation?
