The Jacksonvill Jaguars were an expansion team added to the NFL in 1995. When a new team is created a name must be found for the organization. The team owner could select the name or the team could have a contest to come up with the clubs name. Jacksonville decided to select their team name by a fan contest. The name was selected from a group of finalists which included the Sharks, Stingrays and Panthers, but they decided to go with the Jaguars.
