The first few weeks of the college football season haven't exactly gone to script. While some of the traditional powers—like Ohio State, Clemson and Oklahoma—have yet to look as anticipated, surprise 3–0 teams like Arkansas, Michigan State and Kansas State have climbed into the top 25.
Week 4's biggest matchups include Notre Dame and Wisconsin meeting at Soldier Field in Chicago, Arkansas hosting Texas A&M in a clash of SEC unbeatens and a pair of intriguing Big 12 battles in Oklahoma-West Virginia and Baylor-Iowa State.
