jump shot
An overhead shot taken while jumping
That is exactly what Chong does. She releases it over her head. Watch that video again and freeze it on her release.
No. Chong releases the ball with movement from her chin and collar bone to a point out in front of her face and on trajectory. It is never over her head but is released higher than her head. And as I said uses a different bio mechanics working from different muscle groups.
There is a section of the Stanford game starting at about 12:25 on the game clock where first Stef and then Saniya take shots and the difference between the shots overhead from the brow vs below the chin can be seen ending at about 11:45 on the game clock. It is easy to recognize the different muscle groups used in each shot.
Stef's classic jump shot and release is 15+" higher than her head and swings forward at the elbow forward at release. When saying overhead I mean over her head I do not mean just higher than her head but literally over it and above her head having started at her forehead while in contrast Saniya starts at and slightly below her chin extending forward and up to a point forward and about even to the top of her head or 4-6" higher than her head (but significantly forward) depending on the moment of release which is between frames. It is more push than swing. The ball is never directly over her head. The best view of Saniya's ball position and movement is at 12:50-12:44 on the game clock where she is completely broadside to the camera angle. Clearly, Saniya never has the ball "over" top of her head like Stef, Kaleena, Maya, Diana, Caroline, etc. and the motion moves forward on trajectory to the basket with a push.
