This means that each week you can declare any starting RB as a Mixed Yardage player.
This M.Y. player would then utilize a specialized yardage chart that helps to reflect a player's impact on their game.
This is only good for RB's who get near a 50/50 split in receiving and rushing yards, and does not benefit the "stud"
RB's who also happen to gain decent receiving yardage.
It's more for the "Larry Centers" type of player.
Mixed Yardage players do not use any other yardage charts for rushing or receiving.
