Points per Possession is THE most important stat in BASKETBALL

Here's how a team could have more possessions than their opponent at the end of the game:
In an NBA game, the team that wins the opening tip-off is awarded a throw-in pass to begin the fourth quarter, in addition to starting the 1st quarter with possession of the ball. The opposite team gets a throw in pass to start the 2nd and 3rd quarter.
If a team starts a quarter with possession of the ball and ends the quarter with possession...they will have one more possession than their opponent at the end of the quarter. Teams can start a quarter with possession in two of the four quarters. If the previously described scenario occurs twice, then a team will have two more possessions than their opponent.

Nice video. This stat is overlooked a lot in basketball, eventhough it tells a lot about a game or someone's performance. I think it's kinda comparable to soccer's goal efficiency stat that's used a lot more.

If you find the variance, for any given team, of points per possession, and you assume that the central limit theorem holds for all teams, then you can also use the t-test and confidence intervals. For instance, the variance is usually greater when teams play on the road; you can then find the confidence interval that a visiting team will likely score greater than the home team, assuming you’re only looking at this statistic.

Nice stat.
Now I wonder how someone could predict the amount of possession in a gane

[@PrimeTideSports]

To predict the amount of possessions in a game, you can look at each teams average possessions per game. If you want to get more precise, you can look at how many seconds it usually takes for each team to complete their possessions on offense (and defense).
