Taken in the third round (63rd overall) of the 1996 NFL Draft out of West Virginia, Aaron Beasley overcame an initial stretch of bad luck to become a cornerstone of Tom Coughlin’s secondary. Nagging injuries limited the defensive back to nine games in each of his first two professional campaigns, but his ball skills and instincts were evident whenever he took the field.

Once healthy in 1998, Beasley earned a full-time starting role and became one of the league's top big-play cornerbacks. His breakout arrived in 1999, coinciding with Jacksonville's 14–2 regular season. Playing with outstanding anticipation and recovery speed, Beasley intercepted six passes and led the NFL with 200 interception return yards, bringing two back for touchdowns—including a 90-yard pick-six against the San Francisco 49ers.

Beyond his coverage work, Beasley was an unusually effective blitzing corner. He routinely disrupted backfields off the edge, accumulating 7.5 sacks and forcing six fumbles during his six seasons with the organization. His physical tackling and range made him a vital defender during the team's late-1990s playoff runs.

Contractual changes led to his departure following the 2001 season, after which he signed with the New York Jets before completing his nine-year NFL career with Atlanta.  With the Jaguars, Beasley produced 15 interceptions for 290 return yards, two defensive touchdowns, 7.5 sacks, 305 total tackles, six forced fumbles, and four fumble recoveries.
