A third-round draft pick in the NFL is assured of nothing aside from an honest chance to succeed, maybe even more than one. He will get more consideration than a lower pick, but not nearly as much as a higher one; stuck firmly in the middle of the team's calculation between what it cost to get him and what it would cost to keep him.
Rasul Douglas was the Eagles' third-round pick in 2017, a rangy cornerback with very good hands, solid tackling ability, and eight interceptions in his final season at West Virginia. He was also considered a touch slow and unsuited for press coverage in the NFL, but that is the nature of a third-round pick.
