I think Coop's a lock. The only thing that may have held back his development on an NFL level was coming in as a rookie at 24 years of age. Kupp developed an excellent chemistry with Goff and that has gone thru the roof with Stafford. Cooper & Stafford are like two brothers from another mother, both with incredible football acumen and being coached up by the Brain ... Sean McVay. Just the idea of Kupp & Obj as #1 and #2 WR's for L.A. is damn near euphoric, and while this pairing may be on a temporary hold, I can only dream of what they might deliver in the years to come. Kupp's reception percentage has been over 70% in every year since his rookie season, and 2021 was his best yet at 75.9%, ... so yeah, he's still on a career upswing from what I can see. HoF, you bet !
