This willl simplify a way to put your players on a chart broken down by starters and substitutes for practice or game day. It will help a coach keep track of who is doing what on the field such as assists, goalie saves, goals, etc. so that you can track player stats and players of the game based on performance. It's also a great chart that doesn't require much thinking so that you can coach without worry about the other miscellaneous things going on in the game of lacrosse. It's a great too to manage playing time and it saves on buying yearly roster books from local sporting good stores.
