Cooper Kupp is Isaac Bruce - Veteran with great hands, great route runner and overall great WR
Puka Nacua is Tory Holt - Young and excited and highly productive.
Tutu Atwell is Az Hakim - Super fast and capable of hitting home runs. Not as consistent as the top two.
?????? is Ricky Proehl - Proehl was an overlooked cog on the GSOT who showed up big in big moments (hello NFC Championship game) and almost never caught a ball short of the sticks on third down. Honestly, we could use a Ricky Proehl. Not dynamic, but ALWAYS dependable. Maybe Skowronek could play this part. Sorry Van Jefferson, I know Ricky Proehl, I met Ricky Proehl, and you are no Ricky Proehl.
Tyler Higbee is Ernie Conwell - Pretty good, not great, but shows up every now and then. Decent blocker.
I don't want to push this too far, but I see not exact copies but maybe reflections of the GSOT receiving corps.
