Research reps: High Tide in South Carolina

1 Alabama (5-0, 2-0) at 19 South Carolina (3-1, 1-1), 3:30 ET

Would this be the biggest win in program history for South Carolina?

The highest-ranked opponent the Gamecocks have ever beaten was No. 3 North Carolina in 1981. Prior to last season’s win against then-No. 4 Ole Miss, the Gamecocks were 1-32 against top five opponents.

Indiana (3-1, 0-1) at 2 Ohio State (5-0, 1-0), Noon ET on ESPN

Jim Tressel’s next win will be his 100th as Ohio State's coach (99-21). Only two coaches have reached 100 wins at a Big Ten school in fewer games than Tressel – Fielding Yost and Bo Schembechler (both at Michigan). Each accomplished the feat in their 119th game.

3 Oregon (5-0, 2-0) at Washington State (1-4, 0-2), 5 ET

Oregon is averaging 56.6 points per game, but lost is the fact that the Ducks have allowed seven third-quarter points and no points in the fourth quarter. Oregon is looking for its first 6-0 start since 2002.

Toledo (3-2) at 4 Boise State (4-0), 8 ET

This is Boise State’s final non-conference game of the season. The Broncos have outscored their two non-BCS AQ opponents this season (Wyoming and New Mexico State) 110-6.

Wyoming (2-3, 0-1) at 5 TCU (5-0, 1-0), 3:30 ET

8 Auburn (5-0, 2-0) at Kentucky (3-2, 0-2), 7:30 ET on ESPN2

Auburn is looking for its first 6-0 start since 2004, its undefeated season. Kentucky beat Auburn last season to snap a 15-game losing streak in the series. In 31 all-time meetings, Kentucky has never won two straight over Auburn.

Oregon State (2-2, 1-0) at 9 Arizona (4-0, 1-0), 6 ET

LSU is 5-0 for the third time in the last four seasons. In 2007, the Tigers started 6-0, finished 12-2 and won the national championship. Last year, the Tigers lost to Florida after their 5-0 start and finished 9-4. Florida has dealt the Tigers their first loss in each of the last two seasons.

23 Florida State (4-1, 2-0) at 13 Miami (FL) (3-1, 1-0), 8 ET on ABC

This is the first FSU-Miami matchup without Bobby Bowden on the Seminoles sidelines since Nov. 15, 1975 (24-22 Miami win). Since then, there have been 35 series meetings, with Miami holding a 21-14 edge.

USC (4-1, 1-1) at 16 Stanford (4-1, 1-1), 8 ET on ABC

After posting a 10-31 record in Pac-10 Conference play from 2002-2006, Stanford is 14-15 against conference opponents under head coach Jim Harbaugh.
