The Big Ten is one of only two conferences in the nation to have four or more teams ranked in the top 20 of the Associated Press (AP) poll that was released on Monday, behind only the Big East's five top-20 squads. Ohio State climbs one spot to No. 10 this week, while Nebraska moves up three spots and is now No. 13 in the week's media poll. Purdue checks in at No. 15, while Penn State moves up one place to No. 18 in the AP poll. The ESPN/USA Today Coaches poll will be released on Tuesday.
