The team was co-founded by John Morris and Fred Clark. In September 2008, the team announced that they would use the nickname "Stampede" after narrowing a list of entries down to 3. In the Stampede's inaugural game, they beat an opposing team of American Indoor Football Association All-Stars, 46–26, in the 2009 AIFA Kickoff Classic. In their first regular season game, the Stampede were defeated by the reigning AIFA champion, Florence Phantoms by a score of 19 - 13. In their second ever regular season game, the Stampede defeated the Baltimore Mariners 37-34. After a 2-4 start, Morris fired head coach Kelly Logan and replaced him with defensive coordinator, Mike McDonald. Marques Colston, a New Orleans Saints wide receiver, held a share during the team's first season. Colston left the group after the inaugural season, citing philosophical differences.
