The 2 players that Kupp remind me of are:
Fitzgerald and Rice (I called out Fitzgerald as a good Kupp comparsion and people were saying like Amendola. That is so funny now.)
Neither Fitzgerald nor Rice had great 40 track speed time but played faster on the field than their 40 time would suggest.
Both were physical Wrs that ran great routes and could catch it in tight windows and run after the catch. Both were complete football players.
Long gone on the days are the debates on this board whether Reynolds or Kupp was a better #3 WR for the Rams. Kupp is a top 5 WR in the NFL and right now, many would say he is #1 WR and maybe a top 5 player in the NFL.
