If you're looking for stats that predict winning and losing, an NBA statistical consultant for different franchises over the last few years has come up with four of them.

Dean Oliver's Four Factors:

-Effective FG% (fg% adjusted for 3pt shots). Teams that shoot well score more.

-Rebounding (measured as % of available rebounds your team grabs). Teams that rebound well on the offensive end get lots of second chances. Teams that do the same on the defensive end eliminate their opponents' second chances.

-Free Throws (measured by your tendency to get to the line and make FTs: FTM/FGA). Free throws are generally a more effective way to score than FGs.

-Turnovers (measured by the % of your teams offensive trips down the floor that end in a TO). Turning the ball over guarantees zero points/poss.

You can synthesize all of these items together to come up with efficiency ratings for both teams in a game. Team A's Eff rating is basically pts per trip down the floor.

If you want proof it works, take a look at this link:

The Pacers are 18-1 when they win the efficiency battle and 1-22 when they lose it. The four factors tell you where the Pacers either won or lost the efficiency battle.
