Now six weeks into the season, almost all wide receivers have topped the 150-route mark, and we're getting close to having a trustworthy sample size to draw conclusions from. 350 is the number of routes I typically use as a qualifier if examining a full season's worth of data, but there is a notable dropoff in volatility around the 150-route mark as well.

Chris Godwin leads the league with 264 routes run, and 30 players are already over the 200-route mark. We're at the point in the season where we have just enough data to feel reasonably confident in our understanding of the types of roles these receivers are playing. Surprisingly stellar usage for players like Cooper Kupp, Deebo Samuel, and Mike Williams becomes more and more likely to stick with each passing week. The elevated rates we've seen from budding superstars like Justin Jefferson, D.J. Moore, and Terry McLaurin are beginning to look like legitimately trustworthy trends that support the upward trajectory most expected their careers to continue to follow in 2021.

And even at this point, we're still learning new things at the WR position with each passing week. After evaluating the data and sharing What We Learned in Week 6, I'm ready to lay out my rest-of-season rankings at the wide receiver position heading into Week 7. Here's where I'm ranking each WR going forward, given the data we have through six weeks.

Tiered rest of season WR rankings

Tier 1

1. Davante Adams
2. Tyreek Hill

Tier 2

3. Justin Jefferson
4. Stefon Diggs
5. Cooper Kupp (+4)
6. Calvin Ridley
7. D.J. Moore

I have been hesitant to rank him in a way that is truly representative of his production and underlying volume metrics, but Cooper Kupp has shown absolutely no signs of slowing down. It's really rare for a 28-year-old receiver to make this type of a leap, but we have a 204-route sample size of Kupp drawing usage that is truly unique to only one or two receivers per season. I didn't want to overreact to it, but with each week I become more inclined to believe what Kupp's underlying data tells us -- he is a top-five Fantasy WR who could very well finish the season as the WR1.

L.A.'s Week 6 Usage Report will show a monstrous 40 percent target share and 52 percent air yardage share for Kupp in Week 6, and he now has exactly a 34.2 percent share of both targets and air yards for the season. He has also been targeted on 36.4 percent of his red zone routes, which is the highest rate of any receiver in the NFL. Seeing this type of volume as a member of one of the best offenses in the NFL has made Kupp a Fantasy cheat code.
