6. Jaire Alexander, Green Bay Packers
The Packers played zone coverage on 57% of their snaps in 2019, good for 12th in the NFL. And when they did, nobody was better in a Green Bay uniform than Alexander, the team’s first-round pick in 2018. Alexander’s second NFL season saw him ascend to a status as one of the league’s prime zone defenders, as he allowed 23 receptions on 55 targets for 290 yards, one touchdown, one interception, and a league-best Positive Play Rate of 29.1%. Alexander is an outstanding athlete with the downfield speed to track with vertical routes, and the agility to match up with quicker receivers anywhere on the field.
