The Big Ten went 8-2, including wins by undefeated Illinois, Michigan, Nebraska and Wisconsin, in the final full week of nonconference play Saturday. With Week 4 behind us, let’s take a quick look around the Big Ten: Illinois is off to its best start in 60 years; Indiana must recover from a rough loss, Iowa feels it’s getting better; Michigan hopes this perfect start yields better results, and Michigan State turned to a hot running back.

Minnesota head football coach Jerry Kill readmitted himself to the hospital after suffering another seizure Sunday, according to GopherSports.com.

ESPN College GameDay is coming to Madison this week, according to a recent tweet from the show’s Twitter account. The decision should come as no surprise, considering No. 7 Wisconsin hosts No. 8 Nebraska in the Huskers’ first Big Ten game Saturday. Oh, and the game will be played under the lights, too. We all remember the last time Wisconsin hosted a high-profile night game, right? The result was a commanding 31-18 victory over then-No. 1 Ohio State. Madison was going to be a an electric place either way, but now it will be an even bigger event.

Every week during the college football season, Brent Yarina posts his latest Big Ten Power Rankings. Week 4 saw the Big Ten go 8-2, including wins from Illinois, Michigan, Nebraska and Wisconsin, all of which will bring perfect records into the first week of conference play. As for the power rankings, they are not meant to mimic the Big Ten standings. What fun would that be? They aren’t scientific, either. They’re simply Brent’s thoughts on where each Big Ten team stands after its latest game and entering its next contest. Agree? Disagree? Tweet @BTNBrentYarina.

Following an 8-2 week, the Big Ten added a fifth team to the latest Coaches’ Poll, released Sunday. See both major polls here.

No. 7 Wisconsin and No. 8 Nebraska headline the Big Ten, setting up a remarkable Big Ten opener between the two schools Saturday in Madison. Michigan (No. 19) and Michigan State (No. 25) round out the Big Ten representatives.
