Here’s a quick primer as we enter Week 3:

THURSDAY

No. 3 LSU (2-0) at No. 25 Mississippi State (1-1), 8 p.m. ET, ESPN: The Tigers face their second of three nationally ranked opponents this month away from home. The Bulldogs are still smarting after rolling up 531 yards in total offense last week in a 41-34 loss at Auburn.

SATURDAY

No. 21 Auburn (2-0) at Clemson (2-0), noon ET, ABC: It took a thrilling comeback for Auburn to survive a year ago in this game. Now, the defending national champs go on the road to face Clemson, putting their 17-game winning streak on the line.

Ole Miss (1-1) at Vanderbilt (2-0), 12:21 p.m. ET, SEC Network: Don’t look now, but first-year coach James Franklin has the Commodores 2-0. They’ve had Ole Miss’ number recently, too, winning four of the past six meetings between the schools.

Coastal Carolina (2-0) at Georgia (0-2), 1 p.m. ET, Pay-per-view: The long, hard road to recovering from an 0-2 start begins Saturday for the Bulldogs, who play this one at Sanford Stadium and then play away from home in four of their next five games.

Tennessee (2-0) at No. 16 Florida (2-0), 3:30 p.m. ET, CBS: The real season starts for both teams on Saturday in the Swamp. Both teams have been impressive to this point, but neither has been tested. The Gators have won six in a row in the series.

Navy (2-0) at No. 11 South Carolina (2-0), 6 p.m. ET, ESPN2: The Gamecocks know from experience that Navy is not a team to play around with. One of the most disappointing losses in school history came to the Midshipmen in 1984 when the Gamecocks were 9-0 and ranked No. 2 nationally.

Louisville (1-1) at Kentucky (2-0), 7 p.m. ET, ESPNU: It’s been a rocky start for both teams in the Bluegrass, although the Wildcats have been able to survive each of the first two weeks. Their defense has been superb. Their offense has been disappointing.

North Texas (0-2) at No. 2 Alabama (2-0), 7:30 p.m. ET, Fox Sports South: The Crimson Tide get another tune-up before the big showdown with Arkansas on Sept. 24. It looks like AJ McCarron has established himself as the Tide’s quarterback.

Troy (0-1) at No. 14 Arkansas (2-0), 7:30 p.m. ET, CSS: The Hogs have outscored their first two opponents 103-10 and are 10-for-10 inside the red zone this season. This one has all the makings of a third straight blowout.
