One of the more dramatic and obvious limitations of being an 'older' coach is the inability to demonstrate most intermediate to advanced 'basketball' moves. I don't have the luxury of young, athletic and talented assistants.
But never let what you can't do stand in the way of what you can do. There's a world of great video demonstrations of moves to separate and finish. This all falls under the rubric of 'four ways to score'. You need a 'go to' and 'counter' move to supplement scoring in transition, making free throws, and occasional offensive rebounds. Even if you are a "deadly" shooter, you still need to find enough 'blue sky' to rain down your shot.
You don't need everything on a brief video like this, but you need SOMETHING. It's the rule of 2s, 2 minutes to watch and learn, 2 weeks to practice the move to become comfortable, and 2 months to introduce your new skill into your game.
That's the challenge if you're up for it. Inform FOUR WAYS to SCORE.
