1. Opponent field goal percentage
2. Opponent 3 point field goal percentage (he also cares about how many attempts his defensive is giving up as it can be an indicator of defensive pressure or lack thereof)
3. Fouls
4. Turnovers (he doesn't want them to be able to pass the ball leisurely -- they want turnovers though it may not be the main objective of the defense)
5. Defensive rebounding percentage (wants to know the percentage of defensive rebounds they are getting)
