PMR stands for Player Minutes Remaining and is a term used in fantasy sports, particularly in DraftKings. It is used for sports that have set times associated with quarters, periods, innings, etc. For example, in baseball, PMR is used to indicate how many innings a player has left to play. In fantasy football, PMR is the total of all possible remaining minutes for a player. PMR is important in fantasy sports because it helps players keep track of how much time their players have left to accumulate points and make strategic decisions accordingly.
