As a refresher, the Four Factors are the “Moneyball” stats starting point for basketball statistics and getting a feel for how a team is doing. The link above has the nitty gritty, though the quick refresher is:
Shooting – measured by effective Field Goal Percentage (eFG%)
Turnovers – as a percentage, relative to shots and free throws
Free Throw Rate – those made relative to shots put up
Rebounding – relative to the opponent, for both offense and defense.
