Again it is about the definitions, if you fail to understand the definitions then your interpretation will be based on false premise.
Knock-on: When a player
loses possession of the ball
and it goes forward, or when a player hits the ball forward with the hand or arm, or when the ball hits the hand or arm
and goes forward,
and the ball touches the ground or another player before the original player can catch it.
In the clip the ball did not go forward
and touch the ground or touch another player. Therefore the lack of a catch does not come into the discussion.
Where we might consider a similarity with dropped and then kicked:
- Kick: An act made by intentionally hitting the ball with any part of the leg or foot, except the heel, from the toe to the knee but not including the knee. A kick must move the ball a visible distance out of the hand, or along the ground.
- Drop-kick: After being intentionally dropped to the ground from the hand or hands, the ball is kicked as it rises from its first bounce.
- Punt: A player intentionally drops the ball and kicks it before it touches the ground.
We make a judgment call, as we do throughout the game, that the player either intended or did not intend to drop the ball.
- Intent = Kick, play on
- No intent = Knock on
- Player claiming intent when trying to make the best of a dropped ball = Smile at player and offer "not quite, thanks mate" > knock on.
As the OP likes to expand the hypothetical at a faster rate than the universe. If the player had juggled, dived, caught, rolled and popped what then?
