Defensive Rating (DRAT)
The number of points allowed per 100 possessions by a team. For a player, it is the number of points per 100 possessions that the team allows while that individual player is on the court.
Formula is:
100*((Opp Points)/(Opp POSS)) = DRAT
Where:
- Opp Points - opponent scored points
- Opp POSS - number of opponent’s possessions
- DRAT - defensive rating
