Yes, and also that things like just 40 times at the combine are much less indicative of future success. I think in this scheme it's far more about ability to gain separation (so things like the 3-cone drill and 20-yard shuttle at the combine tell you
much more) and hands.
As you said, brains (can he grasp the offense quickly?), work ethic, etc. all really matter.
Kupp checks
all those boxes. Not that the kid is ever going to be Antonio Brown or Julio Jones or DeAndre Hopkins but he should be very successful for this team for a long time.
