Sin City's first pro football team, the Las Vegas Posse played in the Canadian Football League (CFL) in 1994. Their homefield was Sam Boyd Stadium. The team finished with a 5 and 13 record, folding after just one season. The team was supposed to move to Florida and become the Miami Manatees for the 1996 season, but the CFL left the U.S. before that could happen.
The sweatshirt is great, but the image on the website needs to be updated. A short sleeved shirt is shown and I think that led to confusion with my initial order.
