Guide Hand Nuance:
It is critical to understand how important the guide hand is to the shot.
Most players and less experienced coaches would assume that the shooting hand is key to the shot because its the hand that is actually shooting the ball. But upon closer inspection without the guide hand making contact with the ball, the shot become less effective.
That does not imply you cannot shoot the ball without the use of the guide hand, you can. Technically you only shoot with one hand.
Here is the nuance though. Without that guide hand on the ball the shot feels less controlled.
The litmus test. I have players try both approaches as a coach for a great teaching point. They learn two immediate lessons:
1) One hand Shots- you technically shoot with one hand
2) Both hands - the guide hand feel on the ball becomes crystal clear how it gives more control to the shooting hand
With all the players I have trained over the years in working on their shots, ironically it is usually a guide hand fix that develops or improves the shot.
It is hard for most youth players to fully process what the guide hand does for shooting
