The Posse had notable football talent such as KR Tamarick Vanover, RB Jon Volpe, LB Greg Battle, LB Shonte Peoples, DB/QB Darian Hagan and K Carlos Huerta, and also had rookie quarterback Anthony Calvillo, who would later go on to become the all-time leader in passing yards in all of professional football.

The Posse started with wins over the Sacramento Gold Miners and Saskatchewan Roughriders, but things quickly went downhill, in part due to a lack of familiarity with the Canadian game.

At the team's first home game against Saskatchewan, the singer of the national anthems, Dennis Casey Parks (singing under the pseudonym "Greg Bartholomew"), sang "O Canada", which he had only begun practicing the day before after returning from performing in Japan, to the tune of "O Christmas Tree" after the music system failed.

The incident prompted complaints by Canadians to the CFL, negative press for the new team, as well as a letter from Prime Minister Jean Chrétien to Posse ownership.

[2] On another occasion, Posse head coach Ron Meyer asked the "Showgirls" to loiter behind the bench of the BC Lions in an attempt to distract the opposition.

[6] After the failure of the Milwaukee plans, a group led by singer and business mogul Jimmy Buffett attempted to buy and relocate the franchise to Jackson, Mississippi.

The CFL considered revoking the franchise and awarding a new expansion team to Collins, only to be threatened with a lawsuit from the Posse board of directors.

[7] Another investor for Jackson, Norton Herrick, offered an even higher price than Collins but backed out when he could not secure the money to fund the team through its expected losses.

The Posse's failure meant that the Gold Miners again faced the prospect of traveling extremely long distances for away games.

The Posse was the first attempt by one of the major professional sports leagues in North America to place a team in Las Vegas proper.

Las Vegas had only ascended to major-city status in the 1980s, and even after that most major leagues traditionally avoided it due in part to its gambling reputation.

In the early 2000's, Las Vegas, which has been home to a Triple-A Pacific Coast League team since 1983 was briefly considered by Major League Baseball as a potential new home for the Montreal Expos (who were soon to relocate) but in the end they would move to Washington, D.C. to become the Washington Nationals, in 2016 however Rob Manfred (current Commissioner of the MLB) said the city was a "viable alternative" for a potential expansion team.

[9] The Golden Knights would go on to become the most successful expansion team in North American sports history and make it to the 2018 Stanley Cup Finals in their very first season only to lose (in five games) to the Washington Capitals.

Major league professional football finally settled in the area for good when the NFL's Oakland Raiders relocated to Las Vegas and began play in the city in 2020 playing in Allegiant Stadium in Paradise, Nevada, which replaced Sam Boyd,[10] making Las Vegas the second former CFL city (after Baltimore) to become home to an NFL franchise.
