7 FLORIDA (4-0, 2-0) at 1 ALABAMA (4-0, 1-0), 8 ET

The Gators are an underdog for the first time in their last 40 games. The last time the Gators weren’t favored on the Vegas line was nearly three years ago – Oct. 6, 2007, at No. 1 LSU. In the last 16 seasons, the No. 1 team in the AP poll is 27-0 at home against ranked opponents, with an average victory margin of nearly 22 points. The last AP No. 1 team to lose at home to a ranked opponent was Florida, which dropped a 36-33 decision to 6th-ranked Auburn in 1994. Since the start of the 2009 season, Alabama has outscored its opponents 152-35 in the fourth quarter, including a 31-3 this season.

The Vols hosted No. 7 Oregon and No. 10 Florida.

16 MIAMI (FL) (2-1, 0-0) at CLEMSON (2-1, 0-0), Noon ET on ESPN2

NC State’s 4-0 start is the school’s 12th such start since the inception of the ACC. But extending it to 5-0 could be new for Tom O’Brien. At Boston College from 1997-2006, O'Brien's teams started 4-0 once (1999), but never started 5-0. Also, he didn’t have much success against Virginia Tech while at BC, losing seven of nine meetings.
