NCAA Football Rankings, Week 6: Michigan State drops out of USA Today Coaches' Poll

Coming off their second loss in three weeks, the Michigan State Spartans dropped out of the USA Coaches' Poll Top 25 for the first time of the year this week. The Ohio State Buckeyes knocked off the Spartans 17-16 in East Lansing, Mich., on Saturday.

The Spartans have already played three ranked opponents this season, but they've lost the most recent two match-ups since beating then-No. 22 Boise State Broncos in their season opener. Two weeks ago, the Spartans were ranked tenth in the nation when they lost 20-3 to the then-No. 19 Notre Dame Fighting Irish for their first loss of the season.

Last week, Michigan State was ranked No. 18 in the Coaches' Poll, but 29 different schools received more votes this week, even with Ohio State's absence due to NCAA violations. It's been a rough year for the Big Ten, which has just two teams in this week's USA Today poll: No. 20 Nebraska and No. 22 Northwestern.
