The Story: When the Irish lost 16-14 at home to Northern Illinois on Sept. 7, Notre Dame’s odds of winning the national title ballooned to 100-1. Twelve wins later, including two by double digits in the playoffs, and they are listed at 7-1.

The Buckeyes’ defense will be tested by the high-flying Longhorns, who are 13-2 and rank 21st in scoring. Texas lost to Georgia twice this year but bounced back to beat Clemson in the first round and Arizona State in the Peach Bowl, approaching 40 points in both victories.
