As for the bounce, even if it bounces it was still thrown, so by rule I think it is now 3 points ("...
any ball thrown..."). Before it was only 2 points because the try had ended, but if the ball legally went through, it was scored. Nothing says anything about bouncing, so if it was thrown from outside the arc, it is now 3 points. I agree the intent was probably to eliminate our guessing on the alley-oop, and that is a good change. (We're assuming it was not touched by the offense after the throw.)
If the ball bounces before entering, it must pass through the hoop before the horn sounds or it is dead -- zero points (still).
The collapsing was a joke.
