The 1999 St. Louis Rams
Odds: 300-1 to win the Super Bowl
The 90s were a tough time to be a Rams fan. In 1999, before week 1 of the NFL season, the Rams saw their recent QB signing, Trent Green, suffer a season-ending injury. Vegas set pre-season odds at 300 to 1 for St. Louis to win the Super Bowl. The Rams beat the Titans, 23–16, at Super Bowl XXXIV.
