On a day when No. 1 Georgia went down, No. 2 Alabama had to sweat out two Hail Mary attempts to put away Mississippi State on the road, and No. 3 Notre Dame was hammered, two underappreciated unbeatens stood out.
Wisconsin's defense dominated Iowa a week after the Hawkeyes put up video game numbers against Ohio State to keep the Badgers unblemished. Miami took the fight out of the Irish to stay unbeaten and thump Notre Dame from the College Football Playoff picture.
Oklahoma kept rolling and looking like a sleeper for the playoffs.
It was another wacky day in college football.
