Basketball Question regarding ball direction

I think this is my first sports question on this message board, and I am probably an idiot for asking…so let’s do it!
If a ball is thrown up through the hoop then comes back down through the hoop, are points scored? Also, has this ever happened in an NBA game?

According to this, it’s a violation and a dead ball change of possession to the other team.

How often does it happen in professional play?

I haven’t been able to find any actual occurrence of the ball going through from the bottom and then back down through the net normally in any professional or college game.

That’s not to say that it’s never happened. Just that my Google-fu may not be up to the job.

It seems to me that throwing the ball up through the hoop from below should be worth negative two points, or zero total if it comes back down through the hoop.

That could be an intersting change to the game. If you shoot a basket and score, but do so with the opposing team’s basket, they get the points.

So, if they implemented your rule, then a strategy would be to take away points from the other team by throwing the ball up through the opponent’s hoop.

Not sure how it would work out, and I’m sure there are a whole plethora of reasons why they don’t do it that way, but it would be an interesting twist.

Many years ago, in a college game I was watching on TV, I saw the ball go through from the bottom, on a deflected pass, but it was at an angle and didn’t come back down through from the top.

I don’t think a whistle blew, and play continued as usual.

I saw it happen once. Ball-handler drives and gets fouled so he just throws it up to make it a shooting foul while he was under the basket.

No - not at any level that I am aware of. Certainly not at NBA, NCAA, or high school levels, where I have access to the rule books.
