The 'TND' fields is really just my version of the Tendex rating system. Based on the approximate Point-Per-Possession, each statistical category can be related to the game's scoring. Every time you make a basket, you have made 2 points for your team. Every basket you miss, you lose possession, and subsequently lose 1 point for your team (of course, if a team member gets an offensive rebound, that player will gain possession, and 1 TND point).

Cumulative Ratings are just a sum of the Offensive and Defensive ranking values.

While I IN NO WAY, claim this stat to be an end-all way to rank all the players, I use it to give another data point as to how well a player is contributing to their team.
