Here’s a look at how starters on all 30 NBA teams share the basketball. The
thickness of the gray lines on the accompanying chart represents the average
number of passes per game between two players.
A very clear picture emerges on which teams distribute the ball more evenly
between players, such as the Nets, Bulls and Cavaliers. On the flip side,
Chris Paul and Blake Griffin dominate passing for the Clippers, and likewise
for Kevin Love and Ricky Rubio of the Timberwolves.
下面的图示说明了在30支NBA队伍中，球权流动是如何分布的。附图中灰线的粗细代表平
均每场比赛，两名球员间互相传球的次数。

结果可以明确地指出那些进攻传导非常平均的队伍，例如篮网、公牛和骑士。当然也有完
全相反的球队，像是Chris Paul和Blake Griffin主宰了快艇的传球比重，同样的情形也
发生在灰狼的Kevin Love以及Ricky Rubio身上。
This data would have been virtually impossible to collect in the past.
However, all NBA arenas are now equipped with SportVU technology. Several
cameras are installed overhead which are used to track every move of the game.
The top level center, point guard, shooting guard, small forward and power
forward were selected from all team depth charts. The average number of
passes were calculated from data from this season only (through Tuesday),
taking into account only those games where all five players were active and
saw playing time. In-bounds passes were excluded. Line thickness represents
combined passing in both directions between two players.
在过去这些资料是不可能被收集到的，然而现在所有的NBA球馆都装设了SportVU，许多镜
头从上方追踪球场上的所有动态。
名单上的中锋、控球后卫、得分后卫、小前锋和大前锋是根据每支球队的Depth Chart来
决定的。这些数据只有统计本季的赛事中(到星期二为止)，这5名球员都有真正出赛的场
次。界外发球并没有计算在内。线的粗细包括了两名球员互相传球的次数。
