The early goings of Week 10 have already shown fantasy football owners what rankings and a critical spot such as the flex position can do for a lineup.
As a brief example, those owners who took a gamble in the flex position with Buffalo Bills running back Karlos Williams against the New York Jets on Thursday Night Football received a smooth 10 points.
Williams is the perfect example, too, because he scored most of those points thanks to a touchdown reception, meaning he scored even higher in points-per-reception (PPR) leagues.
Below, let's run down player rankings for the flex spot in PPR leagues, although they apply quite well to standard leagues, too.
