This year at NBA Summer League 2015 in Las Vegas, the league will be tracking five “hustle stats.” These statistics will be tracked in an attempt to quantify how a player’s effort and intensity, factors that are important to team success but traditionally have not been formally tracked, affect the outcome of a game. To do so, the NBA has trained a team of spotters and loggers that will be sitting live onsite for all 67 games.

Here's more info about NBA hustle stats from the league:

The “hustle stats” the NBA will track are:

· 2-Point FG Contested (C2FGA) – Defensive players will be assigned a 2-point FG Contested if they make their presence felt by raising a hand to contest a shot inside the three-point line prior to the release of the ball without fouling or blocking the shot attempt. A 2-Point FG Contested will still be awarded even if the offensive player makes the shot, another player also contests the shot (leading to both players being assigned a 2-Point FG Contested), or the ball is never actually released from the shooter’s hands due to the contest (provided the offensive player demonstrated a clear intent to shoot as opposed to simply pump faking).

· 3-Point FG Contested (C3FGA) – The same rules of a 2-Point Field Goal Contested apply to a 3-Point Field Goal Contested, except the Field Goal Attempt must be outside the three-point line.

· Deflection (DEFL) – A defensive player shall be assigned a deflection upon redirecting the intended flight of the basketball through intentional physical contact on any non-field goal attempt. A deflection is separate from a steal, and does not require either control of the basketball or a change in possession. A kick ball also results in the defending player being awarded a deflection.

· Loose-Ball Recovered (LBR) – A player shall be assigned a Loose-Ball Recovered upon gaining sole possession of a live “50/50” ball not controlled by either team. A loose-ball recovery can occur after a deflection, a block, a field goal attempt, or any other situation in which players must exert effort to gain possession of a live ball not directly in their individually controlled area (i.e. the ball does not come directly towards them or the recovery is contested). A loose ball recovery that leads to a jump ball results in half a Loose-Ball Recovered for both players involved in the jump.

· Charge (CHRG DR) – The defensive player shall be assigned a Charge Drawn if the offensive player dribbling the basketball charges into an opponent that has established a legal guarding position. This occurrence will be directly called by an official on the floor.

In addition to these five new stats, the league is also computing a composite “Hustle Stat.” This is a catch-all numerical representation of the player’s hustle contribution, computed by taking a weighted sum of the five individual hustle stats. Each hustle stat’s weight represents the expected number of points the player contributed to his team through his hustle play.

· 2-Point Field Goal Contested – A contest decreases the probability of a 2-Point Field Goal going in by .05 x 2.0 Point Value of a 2-Point Field Goal = .1 Hustle Points.

· 3-Point Field Goal Contested – A contest decreases the probability of a 3-Point Field Goal going in by .05 x 3.0 Point Value of a 3-Point Field Goal = .15 Hustle Points.

· Deflection – the NBA estimates that the team whose player deflected the ball has a .25 chance of recovering the ball x 1.0 Expected Point Value for gaining possession = .25 Hustle Points.

· Loose-Ball Recovered – Recovering a loose ball increases the probability of possession by .5 x 1.0 Expected Point Value for gaining possession = .5 Hustle Points.

· Charge – 1.5 Expected Point Value for creating a turnover when the opponent otherwise would have likely taken a very good shot (as most charges take place near the basket) + .25 Expected Point Value by drawing a foul on the opposing player (gets team closer to the bonus and limits opposing player’s ability to play) = 1.75 Hustle Points.
