The Jacksonville Jaguars have faced plenty of rival franchises in their short history. Whether the old days of the AFC Central, their playoff bouts vs. the Pittsburgh Steelers, or the modern era battles with the AFC South, the Jaguars have seen enough emotional and pivotal contests in their time to develop some key rivalries. Sports Illustrated recently took a look at the biggest rivals for every AFC franchise, and the pick for the Jaguars should create little surprise: the Tennessee Titans. “The Jaguars are one of the newer franchises in the NFL, as are the remodeled Titans, who showed up in Nashville after the 1996 season,” Sports Illustrated’s Matt Verderame said.
