What to watch today
No. 6 NOTRE DAME at No. 12 CLEMSON
7 p.m., Ch. 5
Records: Notre Dame 4-0; Clemson 3-0
The skinny: Both teams are thinking College Football Playoff and the loser's chances will take a big hit. Weather could play a factor, with forecasts of up to a foot of rain for this weekend because of Hurricane Joaquin. It's the 10th matchup of top 15 teams at Clemson's Memorial Stadium; the last time the Tigers had one, they lost 51-14 to No. 5 Florida State in October 2013 when they were No. 3.
The stat: C.J. Prosise has averaged 8.1 yards per rush (600 yards on 74 carries) for the Irish.
The line: Clemson by 2
No. 1 OHIO STATE
2:30 p.m., Ch. 5
Records: Ohio State 4-0, 0-0 Big Ten; Indiana 4-0, 0-0
The skinny: Indiana fans have waited decades to prove the Hoosiers can compete with the Big Ten's best in football. They have their chance. Ohio State has the nation's longest active winning streak at 17, has won 14 consecutive road games and has lost only twice to Indiana since 1952.
The stat: Indiana has outscored opponents 51-0 in the third quarter this season.
The line: Ohio State by 22
NO. 23 WEST VIRGINIA AT NO. 15 OKLAHOMA
11 a.m., FS1
Records: West Virginia 3-0, 0-0 Big 12; Oklahoma 3-0, 0-0
The skinny: It's the Big 12 opener for both teams, and any conference loss to a team other than Texas Christian or Baylor is damaging to conference title hopes. Oklahoma QB Baker Mayfield could make a leap forward into the Heisman
The stat: West Virginia leads the nation in fewest points allowed (7.7 per game) and turnover margin (3.0).
Line: Oklahoma by 6
No. 5 BAYLOR VS. TEXAS TECH
2:30 p.m. at Arlington, Texas, ESPN2
Records: Baylor 3-0, 0-0 Big 12; Texas Tech 3-1, 0-1
The skinny: Baylor begins its quest for a third consecutive Big 12 title; Texas Tech, coming off a 55-52 home loss to No. 4 TCU, is playing back-to-back top-five teams for the first time. It should be a high-scoring affair: Baylor is No. 1 nationally at 64.0 points per game, the Red Raiders No. 3 at 53.8.
The stat: Of Texas Tech's 29 scoring drives this season, 15 gone under two minutes.
The line: Baylor by 18
No. 3 MISSISSIPPI AT NO. 25 FLORIDA
6 p.m., ESPN
Records: Mississippi 4-0, 2-0 SEC; Florida 4-0, 2-0
The skinny: The Rebels get a chance to prove that 43-37 victory at Alabama two weeks ago was no fluke. The Gators can take a huge step toward restoring the program to its former glory, but they could be without QB Will Grier (illness).
The stat: Ole Miss DT Robert Nkemdiche not only has 15 tackles, including 4½ for loss, but he has also scored three touchdowns on offense.
The line: Ole Miss by 6
