The 2016 NFL regular season is still winding down, but it's never too early to start thinking about next year. Included here is my first run of 2017 rankings at the four primary fantasy football positions. Obviously, a lot will change as a result of offseason research, coaching changes, the draft and free agency, but this is an effort to get an early look at what 2017 drafts may look like.

Additionally, many of you are currently able to stash players in dynasty/keeper leagues. This should help you make some tough decisions. Last year, 'Zero RB' was cool, hip and in, and if you didn't follow suit, you were laughed at. Now that those who picked David Johnson, Le'Veon Bell and Ezekiel Elliott are holding league trophies, and running back is making a comeback. But will the pendulum swing too far back away from wide receiver? It's very possible and, if it does, you should be looking to zig when your opposition zags in an effort to maximize your roster.

Nonetheless, the debate between running back and wide receiver at the top of drafts rolls on. I think some of the disconnect comes because many analysts who do the studies on 'Zero RB' are focusing on PPR leagues. In PPR, top wide receivers will catch upwards of 80 more passes than some top-15 running backs. That's a huge gap and obviously inflates the value of the position. You can't simply apply that 'zero RB PPR' strategy, however, to non-PPR without making adjustments. Consider that the average point total of the top-15 scoring running backs through Week 16 is 212. The average wide receiver total is 162. No. 1 scoring RB David Johnson has scored 323 points, whereas top wide receiver Antonio Brown has 201.
