We’ve reached the midpoint of the season, and Uncle Mo’s Power Index looks nothing like it did seven weeks ago.

Mississippi’s SEC schools came out of nowhere to take the college football universe by storm, while aside from Georgia the SEC East has been a huge disappointment this season. As for Week 7 in particular, a few teams picked up easy wins outside the conference while others battled in classic SEC showdowns.

Uncle Mo watched all the games and did all his homework to come up with these rankings, and he feels pretty good about them. Remember, these are not power rankings, they’re momentum rankings, so keep that in mind when reading through the list.

There’s plenty of shakeup from last week’s rankings, so let’s jump right in:

1. Mississippi State: The Bulldogs are No. 1 in the country for the first time ever, and they’ve now won three straight games against top 10 teams. It’s safe to say they’ve picked up the most momentum of any team in the SEC this season. Mississippi State is one of just six remaining unbeatens in the FBS, and it won’t drop from Uncle Mo’s No. 1 spot until it loses (if that ever happens).

2. Ole Miss: Ole Miss is another one of the final six FBS unbeatens, and it’s the only other team in the conference besides MSU without a loss on the year. The Rebels have won back to back games against ranked opponents themselves, and they, too, have cracked the top 3 of the polls for the first time in decades. Like State, Ole Miss is a fixture on the national radar, and the Rebels are as confident as any team in America entering the second half of the season.

3. Georgia: The Bulldogs established their dominance in the SEC East with a convincing 34-0 whitewash of fellow East contender and defending division champ Missouri in Columbia last week. Georgia routed the Tigers without star tailback Todd Gurley, and a long road trip culminating with an early 11 a.m. CT kickoff never seems to affect the ‘Dawgs. Georgia is a top 10 team and the only ranked team in the East, and following its best win of the year it has to feel great about its chances to contend for a conference title and playoff spot in the second half of the season.

4. Kentucky: Kentucky is 5-1 and tied for first in the SEC East at the midway point of the season. Most Cats fans would have been pleased with five wins all season after the team posted back to back 2-10 seasons in 2012-13. Instead, UK hit the five-win mark in half a season, and now has its sights set on a division title. Can the Wildcats sustain this success all season? We’ll find out in the coming weeks. However, this team is as confident and hungry as any team in the SEC, and it won’t shy away from this week’s road test under the lights in Death Valley.

5. Alabama: The Crimson Tide escaped Little Rock with a 14-13 win over a tough Arkansas team, and although the game wasn’t pretty, it was a huge win for the Tide. Alabama’s defense had its best performance of the season, and the win was a great recovery from a loss to Ole Miss in Oxford one week earlier. Alabama is still a top 10 team with national championship aspirations, and a big road win in a raucous atmosphere (Arkansas was honoring the 50th anniversary of its 1964 national championship team) will boost the team’s momentum going forward.

6. LSU: The Bayou Bengals appeared to be in trouble in a tough road game in the Swamp, but in typical Les Miles fashion they found a way to win the game in the final moments. LSU’s three-point win over Florida was not pretty, but it was huge for the team and for the West division. The West is still undefeated against anyone from outside the West, and LSU was able to post its first SEC victory of the season in topping the Gators. The Tigers now host another East team in Kentucky, and they’ll be feeling pretty good after finally getting on the board in the conference standings.

7. Auburn: Auburn may have lost to the nation’s new No. 1 team last week, but it could have played much worse. The Tigers allowed the Bulldogs to run up a 21-0 lead in the first nine minutes of action, but then out-scored MSU for the remainder of the game. Auburn is still in the thick of the SEC West race, and a loss to a fellow top 3 team did not kill the Tigers’ confidence. It was a setback, sure, but not as much as a typical defeat. This Auburn team is still very alive to defend its conference title, and it knows that.

8. Tennessee: Sure, it was only Chattanooga, but Tennessee’s 45-10 win last weekend was just what the doctor ordered. The Volunteers had lost two heartbreakers to Georgia and Florida entering the matchup with the Mocs, and they appeared to get all their frustrations out with a convincing five-touchdown win. Tennessee’s confidence has been renewed, and if it can find a way to play as well in the fourth quarter as it has in the first three, it’s going to finally earn an SEC win this season.

9. Arkansas: The Razorbacks are easily the most talented team in the nation yet to record their first conference win of the year. In fact, Arkansas hasn’t won an SEC game since 2012, and it has to be feeling frustrated after two straight losses to ranked West teams by a combined eight points. For a 3-3 team with an 0-3 conference record, the Razorbacks maintain confidence after playing these top-flight teams so close. With that said, that confidence might not last much longer. Arkansas needs to get over the hump sooner than later, and Saturday’s showdown with East favorite Georgia is a golden opportunity.

10. Texas A&M: The Aggies have lost back to back games after starting the year 5-0, but to be fair both those losses came to teams currently ranked in the top 3 in the country. Although they were quality losses, A&M is now a longshot at best to contend in the West, which is a huge momentum killer for one of the most exciting teams in the SEC. The road won’t get any easier for the Aggies as they prepare for a tough road test against Alabama in Tuscaloosa this weekend, and they’ve got to be wondering when this impossible stretch of games will finally subside. As we enter Week 8, A&M has still yet to enjoy a bye week, and it’s obvious this team is tired, frustrated and increasingly helpless in a grueling West division.

11. Florida: The Gators missed out on yet another chance to find some traction this season in a giveaway loss at home to LSU, and they now sit at 3-2 overall and 2-2 in the SEC. Florida has been inconsistent on the field and it’s had plenty of distractions off the field in recent weeks as well. The Gators are still searching for answers at quarterback, and suddenly they’re behind three teams in the standings in an already weak SEC East. This isn’t as bad as Florida’s 2013 season, but it isn’t good either.

12. South Carolina: The Gamecocks had a bye last week, providing them a chance to recover after blowing two straight double digit fourth quarter leads to East foes in Missouri and Kentucky. South Carolina returns from its bye to face Furman this weekend, and it has to be feeling better after getting a week to rest and a cupcake non-conference game to fix a few things before rejoining the SEC. The Gamecocks are not necessarily confident at 3-3, but they have to be feeling grateful for the opportunity to regroup with a bye and a game against an FCS opponent.

13. Missouri: Missouri was humiliated 34-0 on its home field by fellow East foe Georgia last week, and the game was actually more lopsided than the score indicates. Any momentum the Tigers brought with them into this game is gone, and although they remain tied atop the East standings it’s going to take them a few weeks to move past this loss. This Mizzou team is clearly a regression from last year’s division champion, and it’s flaws along the offensive line and in the back seven of the defense are obvious. There’s still plenty to play for this season, but the Tigers will have to start again from scratch in building momentum for the stretch run.

14. Vanderbilt: The Commodores actually won their second game of the year against FCS foe Charleston Southern, yet somehow even in a winning effort they manage to leave us shaking our heads. Vanderbilt was fortunate to escape with a one-point win on its home field, and once again the team showed it has no clue who it wants to play at quarterback. There’s no chance any of the teams quarterbacks have any confidence after the way they’ve been rotated all year, and although any win Vandy can score is valuable, this one still did more to expose VU’s flaws than it did to boost its momentum. The Commodores are still the consensus weak link of the SEC, dropping them to the bottom of Uncle Mo’s Week 8 Power Index.
