When Steph Curry made 3s for 5 minutes without a miss, many suggested this was his practice, or the reason that he is a great shooter. Instead, he makes this many shots because he is a great shooter, and these are relatively easy shots: No decisions, no movement, catch and shoot, half-speed shots. This is not practice or skill development.
From an article by David Fleming:
Pregame routines (whether game day or day before a game) are not for improvement or skill development, but for confidence and rhythm. Players want to get the feel for their shot and feel good going into the game because performance is paramount. Improved confidence and rhythm improve performance. Everything is related.
