Best, worst SEC teams after Week 2

The SEC took one on the chin in Week 1 after suffering some losses to lesser competition, but the nation's top conference rebounded in a big way and now have three teams in the Top 25 ranking.

Here is our power ranking for the SEC after Week 2, from worst to best.

14. Tennessee (0-2). The Vols dropped their first two games of a season for the first time since 1988 after an overtime loss at home to BYU, allowing a 70-yard pass near the end of regulation that allowed the Cougars to kick a field goal and force the extra period. On Monday, Jeremy Pruitt compared the football program to the Titanic. Do with that what you will.

13. Vanderbilt (0-2). The other SEC team in the Volunteer State isn't doing much better, thanks to some shoddy quarterback and offensive line play in losses to Georgia and Purdue by a combined 42 points. Up next is LSU.

12. Arkansas (1-1). The Razorbacks lost by two touchdowns at Ole Miss this week and are now 1-19 in their last 20 games against Power 5 teams, have lost 12 straight SEC games, and dropped to 0-9 in league play under second-year head coach Chad Morris.

11. Ole Miss (1-1). The Rebels adopted a run-heavy strategy on Saturday to knock off Arkansas by two touchdowns, but had some issues with turnovers that could cost them against better competition. Mississippi should be over .500 next week with a likely win over Southeastern Louisiana in Week 3.

10. Kentucky (2-0). Good news and bad news for the Wildcats this week. The good: they became one of three unbeaten teams in the Eastern Division: The bad: starting quarterback was lost for the season with a torn knee ligament. Transfer QB Sawyer Smith is up next, but UK has a tough slate ahead of them.

9. Missouri (1-1). After an ugly Week 1 loss to Wyoming, Kelly Bryant and the Tigers got back on track with an impressive W over West Virginia. South Carolina comes to town next week.

8. South Carolina (1-1). Jake Bentley is out and Ryan Hilinski is in at quarterback after the former was injured, and the results looked good: the Gamecocks smacked Charleston Southern by 62 points while racking up a school record 775 yards in the process. Next up is No. 2 Alabama in Columbia.

7. Mississippi State (2-0). Kylin Hill and Tommy Stevens were injured in the Bulldogs' win over Southern Miss. Hill returned, but quarterback Stevens did not with what Joe Moorhead called an upper body injury. Should Stevens be unavailable this week, Keytaon Thompson could come into play after he took his name out of the transfer portal.

6. Texas A&M (1-1). Most people thought the Aggies would lose at No. 1 Clemson, as they did, but quarterback Kellen Mond didn't have a good day in the 24-10 loss. In two weeks' time, A&M will meet Auburn in a game that will have an impact near the top of the Western Division standings.

5. Florida (2-0). Feleipe Franks completed 93 percent of his pass attempts in the Gators' rout over UT-Martin, making better decisions and taking advantage of improved protection. Suddenly, Florida looks like they can hang with Georgia in the Eastern Division race.

4. Auburn (2-0). Bo Nix looked more confident against Tulane a week after scoring the game-winner with seconds left against Oregon in the Tigers' opener. He'll get one more tune-up against Kent State before starting four of his first career SEC games on the road.

3. Georgia (2-0). Ask anybody who knows football, and they'll probably tell you that UGA is the second-best team in the South, but after what LSU did at Texas, right now the Bulldogs get bumped a spot. A pair of relatively easy games to start the season (Vandy, Murray St.) has allowed Georgia to rest their starters in the second half, just in time for their home rematch against Notre Dame, an early season litmus test.

2. LSU (2-0). It's a new day for the Tigers' offense after Joe Burrow threw for over 100 yards to three different receivers in a national statement win at Texas this week. After beating Georgia by three touchdowns last season, LSU only looks better this time around.

1. Alabama (2-0). No one's breaking any news here that the Crimson Tide are still the gold standard in the South and one of the two playoff locks in the nation along with Clemson. Bama hasn't lost to the SEC East in nine years, and this week South Carolina will look to change that. Good luck.

Stanford makes decision on KJ Costello in USC game

Neither of the quarterbacks that started the season for their teams will be on the field when Stanford and USC play each other in Week 2 on Saturday.

Stanford quarterback K.J. Costello was ruled out of the game after taking a hit to the head last week, head coach David Shaw told reporters on Thursday.

Costello exited Stanford's eventual Week 1 victory over Northwestern after he was hit in the head and neck area. He was in a sliding motion when the hit occurred, and officials did not call targeting on the play.

Redshirt sophomore Davis Mills will start in his place.

Mills was a five-star recruit, according to the industry-generated 247Sports Composite, which also ranked him the No. 1 quarterback prospect coming out of high school in the class of 2017, ahead of both Tua Tagovailoa and Jake Fromm.

Southern Cal will start true freshman Kedon Clovis in the game after learning that J.T. Daniels tore his ACL and meniscus in the Trojans' Week 1 win over Fresno State.
