Athletic Play, BUT is it Legal?

If he released the ball in the air, and then grabbed and slammed all without returning to the floor first, legal - as long as the ball wasn't in the cylinder when he grabbed it to dunk.

If he was on the floor and threw the ball up, then his pivot foot returned to the floor, and then he jumped and grabbed it, an official would need to judge whether the "finger roll flip" was a try or a pass. A try - no violation. A pass - violation.
