The next week, in a 41-7 defeat to the New York Giants, he had a season-high seven combined tackles (five solo). In 16 games and 16 starts, he concluded his first season with 23 combined tackles (17 solo), a pass deflection, a sack, and a forced fumble. His 17 solo tackles were second on the team behind Jerrell Freeman (20). In his rookie season, Chancellor already made an impact by leading the team with 17 solo tackles. He also contributed a pass deflection and a sack during that time period. It was reported after the season that Seattle was very interested in trading for Miami Dolphins cornerback Sean Smith but could not agree on terms with him. The Seahawks instead signed Cary Williams from the Washington Redskins to be their starting corner back ahead of 2015. Chancellor was selected to the 2016 Pro Bowl as a replacement for the injured Jalen Ramsey of the Jacksonville Jaguars. He became the first rookie since 1987 to be named to the Pro Bowl. After missing most of training camp with a hamstring injury, Chancellor returned in late July and participated in some practices but was still not 100 percent healthy. On August 26, 2016, he was placed on injured reserve. At the end of the season, he tied Freeman for the team lead with 5 interceptions.
