Draft help?

A RB favored league with points for rushing attempt. Top 30ish players are RBs then running QBs. Two flex and one Superflex. Would it be wrong drafting 3-4 RBs off the rip since they score the most points and can play them in 5 spots?

I think the answer lies in what Mike from the FFballers says - tier based drafting. There’s that top group of 20-25 or so RBs that are really really good, then it tends to fall off a cliff in quality. If you see that you are still in that range in rounds 3-4, then sure it makes sense. But if everyone else is doing the same thing, then I’d go get the quality WRs instead.
