Nice citation johnny d. Thanks.

4.41.4 - Situation B: A1’s three-point try is short and below ring level when it hits the shoulder of: (a) A2; or (b) B1 and rebounds to the backboard and through the basket. Ruling: The three-point try ended when it was obviously short and below the ring. However, since a live ball went through the basket, two points are scored in both (a) and (b). (5-1)

However:

5.2.1 Situation C: A1 throws the ball from behind the three-point line. The ball is legally touched by: (b) B1 who is in the two-point area. The ball continues in flight and goes through A's basket. RULING: In (b), three points are scored since the legal touching was by the defense and the ball was thrown from behind the three-point line.

And we have this rule citation:

A successful try, tap or thrown ball from the field by a player who is located behind the team’s own 19-foot, 9-inch arc counts three points. A ball that touches the floor, a teammate inside the arc, an official, or any other goal from the field counts two points for the team into whose basket the ball is thrown.

Nothing about a defender inside the arc.

This situation is no longer as cut and dry as I originally believed.

Can we all agree that, unlike the original rule from thirty years ago, a three point basket no longer has to be a legal try, but could be a pass?
