Updated fantasy football IDP rankings & tiers for September. Top 75 ranks for NFL defensive players - DL (defensive line), LB (linebacker), DB (defensive back).
Welcome back to our 2017 fantasy football rankings series here at RotoBaller. This an updated look at our overall preseason 2017 fantasy football IDP rankings, including our ranking tiers for each defensive player.
In the fantasy football IDP format, you draft and start individual defensive players instead of an NFL team's entire defense. Individual defensive players score fantasy points based on their individual performance. Fantasy teams can earn points for individual player tackles, sacks, interceptions, and other categories.
Be sure to also check out our Rankings Wizard to see our staff's tiered ranks and auction values for PPR, Standard, and Half-PPR leagues. You to easily filter, sort, and export all sorts of ranks. On that page you can also find more in-depth breakdowns by position.
