When the Jaguars came into the NFL in 1995, they were put into the AFC Central division, so twice a season they played the Steelers, Browns, Oilers, & Cincinnati Bengals.
In ’96, the Ravens were also added to the division.
In 2002 after the Texans were added, the NFL expanded to eight total divisions and the Jaguars went to the AFC South but for seven seasons the Bengals and Jaguars were division rivals. Now they only play when they both finish last in their divisions or when the conferences play each other.
Both of these franchises have been struggling in recent years as the Bengals held the top pick in last year’s draft and the Jaguars held the top pick in this year’s draft.
