John here. RV at 4for4 = Relative Value. It is basically the difference between a player's projected points and the baseline at his position. We use a Core Roster draft plan which means teams will typically draft their starters at each position and a backup at RB and WR before drafting a backup QB/TE. So a 12-team league with roster settings of 1-2-2-1, will have baselines of 12, 36, 36 and 12.

The Full Impact and Top 200 rankings are meant as a general guide to player value and not the end-all, be-all of my 2016 draft plan. Last year was a historically bad year for running backs, so if you run the numbers for 2012-14, you may get different results. This does not mean that you should necessarily draft a RB in the first round. Our projections do not account for the historically higher bust rates among early-round running backs than the early-round receivers. That is something we're talking about, but it's quite difficult to implement.

If you have a flex, you can play with your roster settings to assume that your flex is a WR. This should serve to boost WR value in the early rounds. But a better way to do it is to map out your draft plan for the first 2-3 rounds and then generally follow the rankings the rest of the way. I like the RBs that are available in the 3rd-6th rounds this year, so I'm inclined to start WR/WR (unless Lamar Miller is there in the 2nd) before turning my attention to the RB position.
