This season marked the third time in the last five seasons in which the Jaguars finished fourth in the AFC South. The Jaguars finished with a 2–14 record, not only tying the Kansas City Chiefs for the league's worst record of 2012, but it would also be the worst in franchise history until the team went 1–15 in 2020. Their 1–7 record at home was also their worst home record in team history.
