Fantasy Upside
Stefon Diggs moves from Minnesota to Buffalo where he immediately becomes the clear No. 1 receiver. Although he had a career-high 1,103 receiving yards averaging 17.3 yards per carry, his receptions dropped from 102 in 2018 to 63 last season. But he won't have to deal with Adam Thielen on the other side of the field as there really was a 1A and 1B situation. With the maturation of QB Josh Allen, Diggs is expected to be the deep threat for the Bills which he became last season with the Vikings. He was targeted deep in 2019 in 32% of his targets.
Fantasy Downside
Buffalo was a run-first offense last year, even more than the Vikings. If you remember, Diggs requested a trade mid-season because he wanted Minnesota to throw more. Diggs has been described as moody which hopefully will go away with a new start in western New York. Even though Allen is expected to be better, he is still a slight drop-off from Kirk Cousins so that could hurt his numbers slightly.
2020 Bottom Line
It appears there should be an increase in Diggs' targets which will probably translate to more catches. However, the yardage total from last year will probably take a step back. Diggs projects to have 76 catches for 1,073 yards and six touchdowns which ranks him 23rd in fantasy wide receivers. He has an ADP of 62, but you can grab him a little higher as he can serve as low-end WR2. Diggs will not have his best fantasy season ever, but his value dictates he will help your fantasy team if you can grab him around the fifth or sixth round.
