To recap, gravity score measures how closely a player's defender sticks to him off the ball. Higher gravity scores generally belong to bigs because their primary defender must stay close and also protect the basket. On the other hand, guards typically have lower gravity scores simply because defenders have more liberty to shade off their guy on the perimeter. But elite shooters typically generate more attention off the ball.
Then there's distraction score, which quantifies how much a player's defender is willing to help off the ball to stop the ball handler. The worse he is as a shooter, the more likely his defender will be distracted by the ball handler. To identify the most effective floor-spacers in the NBA, I created a composite score that combines the two metrics. The result is what I've called "respect rating," which has now been translated to a 1-to-100 scale with 100 being the most magnetic (think sharpshooters) and 1 being least magnetic (think non-scoring bigs).
