The basketball went right into the net as time expired.
The end result was that "three points" was credited to the scoring team, giving them the victory by a single point - as a result of the scoring player being well outside the 3-point circle.
In conclusion, what we saw here was a basketball travelling more than halfway across the basketball court and precisely falling through the net. The player throwing this ball seems to have clearly intended for this to happen as he appeared to be aiming directly for the net.
Ahh.... its a well known fact that many less experienced players, when shooting over their heads from well outside the three point line, are not aiming directly for the basket, but are actually aiming for a spot almost ten feet short of that!
