IDP Rankings Dynasty 2025 (Defensive Back)

Off-the-cuff opinions from random guys on the internet are not the best foundation for creating {%fallbackScoringSeoText%} Rankings. You wouldn’t buy a house with a cracked or leaking basement, would you? No! The foundation for anything is critical.

At Draft Sharks, our Dynasty Rankings are based on data—a lot of it. We start with a player's baseline, a weighted average of this year’s projection, and their last two seasons. Then we use 3-year, 5-year, and 10-year fantasy forecasted output. This isn't guesswork. Our process has been built using machine learning for all NFL data since 1999. We determine this output using scientifically-sound performance aging curves and retirement rates. And these numbers are specific to both positional groups and archetypes of players. These are the smartest fantasy football projections on the market. Period.

3D values+ then apply a weighted average of those 1-,3-,5- and 10-year projections and a cross-positional algorithm based on your exact league setup and scoring. The results are an unparalleled single (true) value you can use universally on the site. That means you can use these values for ranking in the preseason, regular season, and trade valuations.

Ready to go for the gold? In the Draft War Room you can adjust the weighting even heavier toward year-one projection in "Win Now" mode.
