Robert Vollman came up with the OZ/QoC chart (a.k.a. player usage charts) as a way to organize how every player on a team performed in a visual manner. Vollman put a chart together for every team in the 2011-12 season and included commentary from people like me (obviously for the Devils chart) in a .PDF (direct link) available at his site Hockey Abstract. It's a good read and something else to pass the time before Game 2 tomorrow. Thanks to Robert Vollman for including me in his project and for putting this together.
