The Big Ten leads all conferences with four of the top 13 teams in the Associated Press (AP), USA Today coaches and Harris polls, as Michigan State has cracked the top 10 in the AP and coaches polls for the first time since the 2003 campaign. The Spartans improved to 7-0 for the first time since opening with nine straight triumphs in 1966 and have now climbed to eighth in all three polls. The last time MSU appeared among the top 10 in both the media and coaches rankings was on Oct. 26, 2003, when the school was ranked ninth by the AP and tenth by the coaches. Three other conference programs rated among the top 13 in the country, including No. 10/11/11 Wisconsin (AP/USA Today/Harris), No. 11/10/10 Ohio State and No. 13/12/12 Iowa. In addition, Michigan and Northwestern are receiving votes in all three polls while Purdue received one vote in the Harris poll.
