The Big Ten remains one of two conferences with six teams among the top 25 in at least one of the national polls after the latest Associated Press (AP) and USA Today coaches polls were announced. The Big Ten and SEC are the only conferences with six teams rated among the top 25 in the coaches poll, while the Big Ten's five teams among the top 25 in the AP rankings rates second only to the SEC. The Big 12 ranks third with four teams among the top 25 in both polls, including future Big Ten member Nebraska, followed by the Pac-10 (three teams), Mountain West (three in AP, two in coaches), ACC (two) and WAC (two). While Penn State dropped from the top 25 after a loss at Iowa, Northwestern returned to the polls for the first time since Dec. 7, 2008, and is ranked No. 25 by the coaches. The Big Ten's remaining ranked squads all appear among the top 20, led by Ohio State at No. 2 in both polls for the sixth straight week. The Big Ten's other top-20 programs are No. 15/15 Iowa (AP/USA Today), No. 17/16 Michigan State, No. 18/17 Michigan and No. 20/19 Wisconsin.
