If you want to go with drafting no RB’s in the early rounds, I have an alternative for you: Get those WR’s (and top 3 TE’s) early, but when you do draft RB’s, go for “young and unproven” later in the draft. Grab guys like Travis Etienne, Javonte Williams, and Michael Carter. Guys with huge upside. If these guys hit, along with your rock-solid WR’s, you’ll be cruising to a championship.
Mind you, I still prefer drafting RB’s early, but if you are so inclined to the zero RB strategy, I think this will help.
