Running backs have been the centerpiece of fantasy football since it's inception. Simply put, they were the most reliable producer of points, and therefore the first choice off fantasy boards. But with the rise of the two back system went the reliability of running backs. And this shift away from running backs hit critical mass in 2016.
That has never happened. We have never had a top 15 that resembled that. Hell, 2007 looked like this:
God I miss Brian Westbrook and dominant Steve Smith.
Anyway, it wasn't just the top of the draft that was wide receiver heavy. There were more pass catchers taken in the top 12, 24, 36 and 48 for the first time. With injuries, multiple back systems, and pass happy offenses, wide receivers were finally the majority.
But the 2016 season, and as a result, 2017 mock drafts, have seen the return of the back and a drop in wide receivers.
So what does this mean for 2017 and the future? The easy way out is for me to say that it all depends on your personal draft strategy. But outside of that rightful top 3 running backs, I still see wide receivers as the wave of the future and the more consistent option. The market on running backs has corrected, but corrected too far. Read: I don't trust Jordan Howard/LeSean McCoy or many of the highly ranked running backs at all.
And for the future, I would proposition that it will be a mix of 2016 and 2017. 2016 was most likely an anomaly, as the top 3-5 picks will still be dominated by running backs. But the changes in how football operates are here to stay, meaning the number of wide receivers taken in the first four rounds will continue to grow. The days of LT, Larry Johnson, and Shaun Alexander are gone for good.
