The Week 4 college football slate provided some separation in the middle of the pack thanks to three matchups of ranked opponents.

The biggest game of the day was a prime time SEC showdown between No. 6 Tennessee and No. 15 Oklahoma, with the Volunteers defense making a statement in a 25-15 victory to improve to 4-0 on the year.

No. 18 Michigan ripped off 290 rushing yards in a 27-24 victory over No. 11 USC where they passed for just 32 yards, while a key game in the battle for a wide open Big 12 saw No. 12 Utah secure a 22-19 win over No. 14 Oklahoma State.

Meanwhile, upstart No. 23 Northern Illinois suffered a letdown in its first game since upsetting Notre Dame, which opens the door for the rest of the Group of 5 field in the coming weeks.

This week’s panel included David Kenyon, Adam Kramer, Morgan Moriarty, Joel Reuter and Brad Shepard. A first-place vote was worth 25 points, a second-place vote worth 24 points and so on.
