Total Points Saved (TPS) is a defensive metric defined as the number of points a defensive player prevented their individual matchup from scoring versus expectation.

Defensive Points Saved (DPS) is defined as Total Points Saved per 100 possessions.

If Player A defended Player B for 17 possessions and was expected to allow 24 points (calculated based on a variety of different factors pertaining to the skill of the offensive player and the situation) and instead allowed 22 points, Player A saved two points over 17 possessions. Player A’s TPS (Total Points Saved) would just be two, while their DPS would be (2 / 17) * 100 or 11.76.
