A better video? This one clearly shows everything! We shouldn't need a zoomed-in camera on the basket to be able to tell it went in!
Here are the freeze frames for those that are still questioning it!
The ball headed towards the basket...

The ball entering the basket — note the position of the ball just inside the rim...

The ball IN the basket!!

If anyone still wants to say they are not sure after that, I have no idea what to tell you!!
