Why would anyone draft a WR2/3 on a team with Nuk, Brown, Green, Ertz and a receiving back in James Conner?
I expect him to have more than 800 yards, but that's not someone I want to draft outside of late, late rounds. The same reasons I wouldn't draft Mecole Hardman, Jarvis Landry, Curtis Samuel etc
It's nothing to do with what he can do and everything to do with only one ball and lots of hands to feed.
Tyler Boyd has 2 1000 yard seasons, had 850 the last 2 years, and his rank is 57 and his ADP #123. For exactly this reason.
