Back in the early days of fantasy football the Zero Running Back Strategy would have made little sense with running backs dominating fantasy points, and leagues utilizing standard scoring across the board. The popularity of PPR leagues accompanied with the evolution of the NFL to a pass happy/multi back league means that blindly drafting running backs doesn't cut it anymore. Driving that point home, only five running backs (Gurley, Elliot, Johnson, McCaffrey, Barkley) had an offensive snap percentage over 65%. Five! And it's not like 65% is an overly high number. Needless to say, wide receivers offer a more consistent and deeper pool of players, and this strategy looks to capitalize on that.
Before we jump into the strategy, a couple caveats. First, all leagues have different rules and players. I'm not prescribing you make this your one and only strategy. Being able to adapt mid draft is essential depending on value and the players drafting. I think it is a particularly good strategy this year, but use all of the information you have to make the right decisions.
