In 16 games, Sanders made 18 of 20 field goals on the year, and this 90-percent field goal conversion rate was the fifth best in team history. He also converted 35 of 36 extra point attempts. Despite missing out on the Pro Bowl in his first season, Sanders was named to the Pro Football Writers of America 2018 all-rookie team.
