Big Ten football power rankings after Week 4: Clear separation at the top.

What did this last week of football mean for our latest Big Ten football power rankings? Did Ohio State move up after its classic win vs. Notre Dame? #B1G

What another wild week of college football, especially in the Big Ten. Two games in the conference went to overtime, and Ohio State pulled out a classic thriller in South Bend, Indiana over a top ten Notre Dame squad.

Aside from that, some of the other results held form and that means that teams like Michigan, Penn State, and Ohio State are still considered among the best in the league — especially as we sort through our power rankings after all the action from Week 4. Meanwhile, teams like Iowa, Minnesota, and Michigan State appear to be headed in the wrong direction.

Believe it or not, the college football season is moving right along as we look at our Big Ten college football power rankings after the 1/3 mile marker of the season.
