The Denver Broncos have totally rebuilt their wide receiver room since Sean Payton arrived, and the one lone presence in the room has been Courtland Sutton, who has turned into a very efficient target for Denver, especially on third and fourth downs.
Well, in recent years, Denver has drafted receivers like Marvin Mims Jr, Devaughn Vele, Troy Franklin, and Pat Bryant. The team traded Vele to the New Orleans Saints before the year began, but they have seen guys like Franklin and Bryant show signs of being something notable.
Mims seems to still be in that 'gadget-y' type of role on offense, and that might simply be who he is.
