Drafting based solely on overall rankings is never a good idea. You want to draft based on tiers and drop-offs in value. It’s important to know the projections for each position group and how the groups compare to one another.That’s critical to our “Draft Chasms of Doom” series, which began last season. In it, we discuss each skill position and try to articulate how and when to draft within each group and among them.With quarterbacks (in 1QB leagues), the question this year is whether to draft Josh Allen, one of the top-six QBs, or wait even later so as to maximize picks at wide receiver, running back and even tight end. For RBs, there are, of course, value cliffs up top (Bijan Robinson and Jahmyr Gibbs are the elitest of elite options). But the real takeaways are that grabbing an RB in the first three tiers is essential, and there is a real drop-off after the top-33.For wide receivers, the gap between the top-two (Jaxon Smith-Njigba and Ja’Marr Chase) and even WR10 is massive, and the top WRs have higher projected Value Over Replacement Player (VORP) totals than the top RBs. So, spending big very early on the WR group isn’t a bad idea, even though the top RBs may be ranked higher overall on our platform and many others. But, if you miss out on JSN, Chase, Puka Nacua and Amon-Ra St. Brown, the decline becomes more gradual (as illustrated in the chart below), and you may want to pivot back to RB, certainly before drafting anyone after A.J. Brown.
