The receiver has already worked with some of the best quarterbacks ever. Because his grandfather played with Archie Manning and remains friends, Kupp has worked at and been a camper at the Manning Passing Academy. He said he caught passes from a couple of guys named Peyton and Eli.
The first time Kupp ever spoke to Peyton Manning, he was telling him to run a specific route.
"He comes up and says, 'OK, I want you to take an angle inside the 6, I want you to push it up to 12, double stick, hit the near upright, and I'm going to hit you at 44 yards,' " Kupp recalled. "I run it, I go back and watch the film afterwards and he dropped the thing at 44 yards exactly."
