Ah, Hopkins slipped my mind, Julio as well, but he's old now.
Kupp is just beginning his career and dominating, that's why I have him on top.
Evans is another good WR I'd put in top tier. I just don't have Golladay, Allen, Adams that high...
Diggs is under Thielen in my book.
Tyreek is definitely dangerous but he's more of a gadget guy than #1 WR material.
