Predicting the Heisman Trophy winner is no easy task, especially in a season as crazy as 2009. For the first time since 2002, the current version of the Heisman Predictor failed to identify the winner.
But all is not lost. This year's outcome was a learning experience. The very premise of the Heisman Predictor is to identify voters' tendencies, which certainly change over time. So whether the formula worked or not, it must be re-evaluated each offseason to make sure it still accurately accounts for the criteria that are most important to the current set of Heisman voters.
Perhaps the best example of how the award has changed over time is that for three consecutive years, a sophomore has won the award. Any attempt to create a Heisman Predictor 10 to 15 years ago certainly would have included a penalty for underclassmen. However, the current version of the formula recognizes that voters are no longer preoccupied with the player's class status. This is a significant reason only six years of data (2003 to 2008) were analyzed in the creation of this year's formula.
Typically, voting tendencies change gradually. For example, it's hard to pinpoint the time when the voters began heavily favoring quarterbacks. As the spread offense has taken over the game, voters simply have adjusted their votes accordingly.
