I can easily see him finishing the season with 800 and 5. I projected him for 960 and 6.
FBG has his ADP at 48--end of the 4th round.
5th round receivers: Josh Gordon(who I also don't trust) had decent production last season.
Marvin Jones: 1000 and 9 last year, better QB.
6th Round: Corey Davis, Crabtree, Hogan
7th: Watkins, Goodwin, Edleman, Fuller, Sanders.
Footballguys has Goodwin and Crabtree ranked above him despite the differences in ADP.
I can see several of those guys giving you similar production, and you can get them all much later. If I was getting Robinson in the 7th/8th, maybe I can't resist the upside. In the 4th round--I'd rather regret him having 1200 yards than regret him having 800.
Depending on where you pick in the 4th--Fitzgerald is going off the board at ADP 38, which feels absurd. Landry won't break any yardage records, but based on the pre-season, the target volume appears reliable. You've got JJSS, Drake, Ajay, Tate. I've seen Doug Baldwin and Collins slip into the 4th in several mocks.
