TrueHoop recently investigated a seemingly simple aspect of the NBA game: the traveling violation.
The question is basic: If you're dribbling the ball in the NBA, and you pick up your dribble ... how many steps can you take before you have broken the traveling rules? It's a fundamental part of the game. But I asked several NBA players, and the answers were far from simple.
In addition to asking the players, TH's Henry Abbott also talks with some NBA officials, gets the low-down on how the call is really made, and makes an argument that the rule should be rewritten. The intro to the series is here.
