Social network analysis of soccer map on the game field

Working on visualization of small groups coordination (playing a pervasive game), I ran across this network analysis and soccer webpage. I already blogged about it, but there seems to be new developement such as the mapping of the social network on the game field:

Why do I blog this? I am heading in another direction since my visualizations are less related to social network, and I removed the game field, I only kept the distance between players as an indicator. Anyway, what is interesting in this sort of soccer viz is the kind of question it allows to answer. In this case, it is mostly about Who was on the receiving end of the most passes? Who controlled Rapid’s play? Which players were involved in the most combination pass plays? Who played together with whom and who didn’t? and so on.
