7. Kurt Warner (QB-STL,ARZ)
Nothing has been, nor will ever be more improbable than the 1999 season of St. Louis Rams quarterback Kurt Warner.
Just years earlier serving as a grocery store manager, Warner went on to fill in for the injured Trent Green and capture the NFL MVP and Super MVP for head coach Dick Vermeil.
All in all, Warner won one Super Bowl while playing in three. Incredibly, Warner is the owner of the three most prolific passing days in Super Bowl history (414 passing yards in Super Bowl XLI, 377 yards in Super Bowl XLIII, and 365 in Super Bowl XXXVI).
