It is not what you teach, but what you emphasize.
You aren't going to win championships unless you make layups and free throws.
Winning a postseason game is like winning five regular season games. There is just no feeling like it. Everything is magnified. Every free throw, turnover, shot and play.
If you have to 'try hard' to 'try hard, you are already beaten.
Put your two best players away from the ball and bring it back to them.
Good shooters take the shots; best shooters take most of the shots.
