Players chosen in the top couple of rounds of any given NFL draft aren't just expected to make the roster; they are expected to quickly become impact players for their new teams. This was the case for wide receiver Parris Campbell when the Indianapolis Colts took him in the second round of the 2019 draft.
But Campbell, due to a series of injuries early in his career, was unable to do much of anything to help Indy. In his first three years combined, he played in only 15 games and had a total of 34 catches. That is the kind of production a team might hope to get from a sixth-round choice, not someone in round two.
