Read the rules
@Hawk_4shur posted and then ask if that rule was violated.
1: Maybe, that is what we are looking for in a close up video or one from a better angle. If his hands were on the rim when the ball entered the basket than it is a clear basket interference violation.
2: No - I think we all agree he did not touch the ball
3: No - Again, I think we all agree he did not touch the ball
4 and 5: I've seen no evidence of him grabbing the ring to the point it moved, which is why I was hoping for a close up video.
