Answer
The answer is Super Bowl XXXIV. In the 1999 NFL season, Kurt Warner, the undrafted quarterback for the St. Louis Rams, led the "Greatest Show on Turf" offense to new heights. Despite a disappointing loss in the NFC Championship Game, the team rebounded and defeated the Tennessee Titans in Super Bowl XXXIV, earning Warner the Super Bowl MVP award and cementing his place as a legendary underdog in football history.
