The defining sports game of this decade occurred at University of Phoenix Stadium on February 3, 2008. That night, in a game that moved about as quickly as the clock in Tecmo Super Bowl, the New York Giants upset the unbeaten New England Patriots, 17-14, to win Super Bowl XLII.
It is debatable whether Super Bowl XLII is the single best game across sports in the Aughts; however, it is almost certainly the game that crystallizes the two competing movements in sports this decade: the quest for historical transcendence and the ascension of the postseason underdog.
Sports are too broad and diverse a subject to write a coherent essay that addresses what happened in the Aughts. Too much happened to be melded into a sustainable theme or argument. And although for many the story of the Aughts is what occurred off the field—be it scandals surrounding performance-enhancing drugs, referees, or personal conduct—to me, the defining narrative of sports in the Aughts is of those two competitors in Super Bowl XLII: the unbeaten Patriots and the pedestrian Giants.
