I thought posters might find of interest the "shot chart" that Notre Dame does. For an example, Notre Dame's recent 3-0 loss to St. John's, see http://und.ocsn.com/sports/m-soccer/stats/090603aaa.html#GAME.CHT about halfway down the page. I like the way they separate the areas of the field. Doing this kind of tracking seems quite simple and easy. St. John's took 9 shots, 5 from inside the area. All three St. John's goals were scored from inside the area. In contrast, Notre Dame took 12 shots, but only one inside the area. I have heard it said that about half of all goals are scored from inside the area. Does anyone know whether this is in fact true? Here's another subject for a good longitudinal statistical analysis.
