Should 1 RB, 3 WR be the new default?

I'll admit part of this is sour grapes. I'm leaving at least 40 points on my bench every week due to having five WRs who put up 20-point games regularly. Meanwhile my RB situation is a shitshow. I started the season with Peterson and Spiller. I replaced Peterson with Bradshaw, and Spiller with Hillman, and thought I was in decent enough shape. Two weeks later and I'm screwed again.

But you would think with five stud WRs, I could swing a trade with someone, right? Wrong. There's two guys in my league with two undisputed RB1s, and they don't need my WRs, even at a two-for-one rate. Everyone else is stacked at WR too. Meanwhile the other ten teams are either hanging onto one RB1 and some scraps, or total scraps. Unless you have a lot of byes, the FLEX spot is a de facto WR3 spot, and the biggest determining factor in your victories is which WRs you bench.

Check out the list of top 25 preseason RBs on Fantasypros. Ten of those guys have been non-factors for at least half the season, either due to injuries, suspensions, or losing snaps to backfield committee. That's a 40% chance of getting nothing out of some top draft choices. Meanwhile look at the top 25 WRs. There are some up-and-down players (as with any group), but the only one on that list who has missed significant time is Megatron.

IMO, RB2 is starting to become a relic of the 1990s. Nowadays it makes more sense to have a WR3 starting spot and have the FLEX be between RB2 and WR4.
