3. Jourdan Lewis, CB
One of the shining aspects of the Cowboys' campaign has been the cornerback room. While Trevon Diggs (before his season-ending injury), Stephon Gilmore, and DaRon Bland are the main reasons behind that success, it seems like Jourdan Lewis didn't get the memo.
Lewis, who was drafted 92nd overall by the Cowboys in 2017, has been awful throughout the season. The 28-year-old has allowed 37 catches for 416 yards and three TDs on 61 targets and has allowed opposing QBs to play to a 97.4 passer rating — the highest mark of his career.
If that isn't bad enough, Pro Football Focus has Lewis as the Cowboys' worst-graded player in coverage (35.2) while his 42.5 overall defensive grade ranks fifth-worst among 123 qualified cornerbacks in the NFL.
Lewis is also heading to free agency this offseason and there's just no incentive for the Cowboys to bring him back. His best days are behind him and it's time for Dallas to move on.
