How is the driving skill of your players? You played 'look inside' which has an increased pace. Your players will shoot more often, even when they are not open. To be sucessful in this case, they need higher driving.
With a lower tempo game, I find you need guards who can handle the ball and pass well. That will avoid turnovers and set your players up for better shots.
That being said, your tactics were sounds. You were going to miss more shots but you had a huge rebounding advantage.
