Injury concerns aside, Slots 4, 5, 6 aren't usually amazing Wrs on most teams. They're going to be young guys that need
need time or possesion WRs. I have no clue what some of these guys on the roster are capable of upside wise, but I have little doubt they could fill those depth roles just fine. There will be injuries though so for sure should be trying to get a few more goto guys in the mix would be good, but there's a Skyler Ridley or Colby Pearson on this roster that just needs PT to show they're better than you thought.
