With three weeks remaining in the season, the Heisman race is coming into focus. The Texas A&M Aggies' upset of the Alabama Crimson Tide knocked Bama QB A.J. McCarron from the mix, leaving us with just five viable candidates as we enter the home stretch.

Rather than present the Heisman Predictor standings this week (which still have Kansas State Wildcats quarterback Collin Klein in the lead), let's take a look at what each of the five remaining candidates need in order to hoist the trophy on Dec. 8 in New York City.

The candidates are ranked here based on their odds of winning the award.
