What is the Optimum PF?
The Optimum PF (points scored for team) is the aggregate total of points a team would have achieved if an owner had chosen all of the top scoring players from their roster, including their IR and Taxi Squad. The percentage that shows on the Leaders tab underscores the degree to which an owner starts their best scorers over the course of the season.
The Optimum PF is also used to calculate the Coach Rating, which compares the optimum lineup with the actual lineup. An owner who leaves less points on the bench will have a better rating.
