NBA to track Hustle Stats at summer league
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.
