3. Trevon Diggs
There's a reason why the Packers drafted Eric Stokes in the first round of the 2021 NFL Draft. Poor play in the secondary (outside of Jaire Alexander) led to the Packers' downfall in the NFC Championship loss to the Tampa Bay Buccaneers three months earlier.
The Packers could've avoided their disastrous defensive performance against Tom Brady had they drafted Trevon Diggs the year before. Diggs has become a first-team All-Pro and two-time Pro Bowler with the Dallas Cowboys. In Green Bay, he would've formed an elite cornerback duo alongside Alexander.
Diggs is a game-changer. He has 18 interceptions, including two pick-sixes, in 47 career games for the Cowboys. He led the NFL with 11 picks in 2021.
According to Pro Football Reference, Diggs has never allowed a passer rating above 86.1 in his coverage in any of his four seasons in the league. In 2021, quarterbacks throwing his way earned a passer rating of only 55.8. He gave up four touchdowns but made 11 interceptions.
The Packers would've had two top-10 cornerbacks starting in the secondary. Had Diggs started opposite Alexander in 2020, perhaps Green Bay would've defeated Tampa Bay in the NFC title game. Instead, cornerback became a concern, leading to the Packers drafting Stokes the following spring.
