Shooting Defaults
You can tell a person a million different things to focus on when you’re coaching their shooting. But, without a doubt, they cannot concentrate on so many things at once, especially in a game. In a game, they are just going to shoot.
Therefore we need to make sure that their default setting when shooting is simply “get the ball through the hoop”. If they start worrying about their arms or legs or hands in a game, they will not be able to control them all and will likely miss. We can work on that sort of thing in training, using repetition and player-led feedback, but on court we need to just let them try and score.
This, then, is something that needs to be put in players from the start (see the 3rds/4ths section), and can work in conjunction with Focus.
