A lack of upsets at the top of college football resulted in little movement at the top of the Associated Press Top 25 poll on Sunday, as Oregon remained undefeated and keeps its hold on the No. 1 ranking after avoiding an upset at Wisconsin. The Ducks (11-0) prevailed 16-13 in Madison, Wis., while No. 2 Ohio State (9-1), No. 3 Texas (9-1) and No. 4 Penn State (9-1) all won as well, preserving the top four. Indiana (10-0) remained No. 5 after a bye week. Previous No. 6 Tennessee lost to Georgia, and previous No. 7 BYU was upset by Kansas, opening the door for Notre Dame (9-1) to move up to No.
