11. JAIRE ALEXANDER, GREEN BAY PACKERS
At just 22 years old, Jaire Alexander is one of the youngest players on PFF’s top-25 list. He excels in both man and zone coverage from both press and off-man alignments, and despite spending 36% of his 608 coverage snaps in press coverage on the line of scrimmage, Alexander allowed the third–lowest completion percentage (56.1%) and recorded the second-best forced incompletion percentage (20.4%) among cornerbacks who saw at least 90 targets over the course of the season.
Even though he has a smaller frame than Gilmore and Sherman, the 5-foot-10 Alexander typically draws the difficult assignment of covering the opponents’ No. 1 wide receiver. However, he still allowed only an 87.8 passer rating (41st among corners, one spot above Casey Hayward) and broke up 13 of the 98 passes that were thrown his way. As experience contributes to his development, Alexander is sure to remain a fixture among the top players at his position.
