Some good thoughts from Santa Clara assistant Sam Scholl (a former USD Torero) in SC's regular email newsletter:
1. Remind your players that 90% of the game is played without the ball.
2. Never run something in a game unless you have worked on it in practice.
3. Your game plan is only good for about the first six minutes. The rest of the game is all about making adjustments. You should always formulate a game plan going into a game, but your team's success will depend on your ability to make the correct adjustments.
