I get that, but I was making the point that the ball going toward the end line is meaningless. The ball could rebound toward the end line from almost any angle without striking the back of the backboard.

The only "proof" it hit the back, based on angle alone, would be if it went toward the center of the base of the backboard after coming from outside the edge of the backboard.

Better... unless you KNOW it hit the back, it didn't hit the back.
