Chancellor was a four-time Pro-Bowler and two-time second-team All-Pro in his eight seasons with the Seahawks, recording 606 career tackles, 12 interceptions, nine forced fumbles and 44 passes defensed. Chancellor was also a three-time team captain and was twice voted the winner of the team's prestigious Steve Largent Award.
Chancellor also saved some of his best performances for the postseason as the Seahawks went to back-to-back Super Bowls, winning Super Bowl XLVIII in dominant fashion thanks in no small part to Chancellor, who recorded nine tackles, an interception and two passes defensed, and perhaps most significantly, a tone-setting hit on receiver Demaryius Thomas on Denver's third play from scrimmage. A year later in a Divisional Round win over Carolina, Chancellor turned in one of the best individual performances in Seahawks postseason history, recording 10 tackles, a 90-yard interception return for a touchdown, and a line-hurdling blocked field goal.
