Term Definition
Defensive Plus-Minus

#### A metric that measures the difference per 100 possessions in points allowed with a player on the court versus off the court. The accuracy of this measure varies dependent upon how often the player is on the floor and whom the player share it with. In most cases it provides a good indication of a player’s overall defensive value to his team.

Defensive Rating
Author: Dean Oliver

#### A metric which is invented by Dean Oliver. The premise of individual defense is that players force "defensive stops", preventing the other team from scoring.

An individual can do that by forcing a missed shot that then gets rebounded by his team, by getting a defensive rebound, by forcing a turnover, or by fouling a player who misses both foul shots, the second of which is then rebounded by the defense.

Defensive Stop

#### A defensive stop occurs when a player or team defense regains the ball without allowing the opponent a scoring possession.

Ways to get the "defensive stops" done:
1. Forcing a missed shot that then gets rebounded by his team,
2. Getting a defensive rebound,
3. Forcing a turnover,
4. Fouling a player who misses both foul shots, the second of which is then rebounded by the defense.

Diamond Rating
Author: Kevin Broom

#### A metric which is invented by Kevin Broom who devised a simple general formula that works with any per-minute statistics. Fomula subtracts the player's rating per game from his rating per 40 minutes to figure out how much his per game stats undervalue his potential contributions. He then subtracts league average from the player's per-40 minute rating and adds this amount to ensure the player is actually playing well in the minutes he does get.

Diamond Rating Formula=(Per Minute Rating)*40-(Per Minute Rating)*(Minutes Per Game)+[(Per Minute Rating)-(League's Per Minute Rating)]*40

Comments: The fewer minutes a player plays per game, and the better he does in those minutes, the better his Diamond Rating.Diamond Rating makes sense to eliminate players from consideration who are over 27, have more than five years experience, play more than 30 minutes per game or played less than 250 minutes total.
