The Heisman Predictor has proved to be an accurate measure of the likeliest winner of college football's ultimate individual prize. For the formula behind the Predictor, read this.

Following the Heisman Trophy race on a week-to-week basis provides perhaps the best evidence of how thrilling the college football season can be. We're just three weeks into the season, and only three of the Heisman Predictor's preseason favorites remain in the top 10: Terrelle Pryor, Kellen Moore and Mark Ingram (who left briefly while he was injured but has since re-entered the discussion).

This week the order of the top 10 remains relatively unchanged, but three newcomers give the standings a fresh look. Jake Locker, Case Keenum and Trent Richardson all fell out of the race -- at least for now -- opening the doors to these new candidates.
