The preseason may or may not be meaningless, especially when the Lions go undefeated in the 2008 preseason and then don't win a single game in the regular season. But at the same time, preseason records have been at least somewhat indicative of future success. The past 15 Super Bowl winners have a combined preseason record of 39-23 (.629) in the preseason in which they win the Super Bowl. The 2008 Steelers went 3-1, but the 2007 Giants went 1-3 as they upset the then undefeated Patriots in Super Bowl XLII. New England went 2-2 in that preseason before winning 18 consecutive games, including playoff wins over the Jaguars and Chargers.
