Basketball State makes heavy use of "tempo-free stats." Perhaps "possession-based" is a more apt term, as they all use the possession as their cornerstone. Standard statistics use per-game averages. Even though games sometimes go into overtime, the possession provides a more consistent apples-to-apples basis of measurement. These stats are highlighted in blue in the list below.
