Off-the-cuff opinions from random guys on the internet are a horrible foundation for creating Dynasty Rookie Rankings.  

But that's mostly what exists when you search for anything from "non-PPR rookie rankings" to "best dynasty rookie picks."    
At Draft Sharks, our Dynasty Rankings are based on some serious "fantasy football AI." Here's what we go through in creating Dynasty rankings:

1. We start with a player's baseline, a weighted average of this year’s projection, and their last two seasons. 

2. Then we create 3-year, 5-year, and 10-year fantasy forecasted output, by using scientifically-sound performance aging curves and retirement rates. These are the smartest fantasy football projections on the market. Period. 
3. Now comes the fun part... We create a "Dynamic Most Valuable Player-Plus" value (DMVP+ for short) that's applied to a weighted average of those 1-,3-,5- and 10-year projections.

The results?

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.
