Spurs chart doesn't fully represent their passing. It shows a lot of Parker and Duncan passing to each other but they're a great passing team. They're a rival but I can't deny I love watching them play
These can definitely be misused. For example, Terrence Ross looks like a black hole. But in reality he is a catch an shoot guy who doesn't get a ton of touches and only puts up 9 shots a game.
It's really fun to take a look at one of these and try to picture how the offense flows just by looking at the distribution of passes.
