The Associated Press Top 25 has a new look following Week 4 of the season. With the Big Ten, Pac-12, Mountain West and MAC set to play football next month, the AP poll has added those teams back into its weekly rankings. 

Most noticeably, Ohio State is back in the poll at No. 6. The Buckeyes will play their first game on Oct. 24 against Nebraska, and are a favorite to make the College Football Playoff yet again. Other new additions include No. 10 Penn State, No. 14 Oregon, No. 19 Wisconsin and No. 23 Michigan

Other big movers from the weekend include No. 3 Florida, which rose two spots after beating Ole Miss in its first game of the season. This marks the Gators' highest ranking in the AP Top 25 since Oct. 21, 2012.

The two teams that fell the hardest were LSU and Oklahoma, at 14 and 15 spots, respectively, following their Week 4 losses. Mississippi State, which beat LSU 44-34, is up to No. 16.
