The first College Football Playoff rankings were released this week and the SEC reigns supreme with the top two teams. Those two, Georgia and Alabama, are back in action fresh off their lofty rankings. Both have testers at home against intra-division opponents.

Here’s a look at all nine games on Saturday that involve SEC teams, and the matchups that could make the difference.

Auburn (6-2, 4-1) at Texas A&M (5-3, 3-2)

Noon

Tigers’ depleted backfield vs. Aggies’ run defense: With Kamryn Pettway sidelined with a shoulder injury, the Tigers’ run game rests in the legs of Kerryon Johnson, who leads the SEC averaging 120.5 yards per game. Can he hold up, or will Kam Martin step up his game, against an Aggies run defense ranked 10th in the conference after giving up 232, 236 and 228 rushing yards in its last three games?

UMass (2-6) at Mississippi State (6-2, 3-2)

Noon

UMass run game vs. MSU defensive front: If Minutemen QB Andrew Ford (neck) isn’t able to go or isn’t 100 percent, it puts added pressure on a UMass run game that’s only producing 101.33 yards per game away from home. MSU ranks third in the SEC, yielding 123.75 rushing yards per game.

Florida (3-4, 3-3) at Missouri (3-5, 0-4)

Noon

Gators’ mental status vs. Missouri’s push for bowl game: With all that’s going on in the Florida program, interim head coach Randy Shannon will have his hands full trying to get the team focused on the task at hand. Florida will try to halt a three-game losing streak by slowing down a Missouri team that has won two straight.

Western Kentucky (5-3) at Vanderbilt (3-5, 0-5)

Noon

Hilltoppers’ passing attack vs. Commodores’ secondary: Western Kentucky QB Mike White has thrown for 300-plus yards in each of his last three games, and four of five. Vanderbilt ranks fifth in the SEC against the pass, giving up 171 yards per game. It’s strength vs. strength.

South Carolina (6-2, 4-2) at Georgia (8-0, 5-0)

3:30 p.m.

Gamecocks’ formidable run defense vs. Georgia’s relentless rushing attack: Now that they’ve reached No. 1 status, the Bulldogs must remain focused on a South Carolina run defense that has held its last three opponents to 120 yards or fewer. Twice before that, the Gamecocks held the opposition to under 100 yards rushing. How it handles the SEC’s second-best run offense, led by Nick Chubb and Sony Michel — that has been held under 200 yards just once this season (Notre Dame) and has rolled up 1,379 rushing yards over the last four games — will be fun to watch.

Ole Miss (3-5, 1-4) at Kentucky (6-2, 3-2)

4 p.m. 

Ta’amu vs. Swiss cheese pass defense: Losing Shea Patterson was supposed to be the last straw for the Ole Miss season. But QB Jordan Ta’amu stepped up last week and threw for 368 yards, not to mention running for another 76. What he does for an encore against a Kentucky pass defense that ranks last in the SEC and 112th nationally, giving up an 266.6 passing yards per game, will go a long way in deciding this one.

Coastal Carolina (1-7) at Arkansas (3-5, 1-4)

4 p.m.

Razorbacks’ ground game vs. Coastal defensive front: A very average run game could get healthy this week for Arkansas. With a middle-of-the-pack rushing game, the Razorbacks are licking their chops at a Chanticleers run defense that gave up 238 yards to Texas State a week ago.

Southern Miss (5-3) at Tennessee (3-5, 0-5)

7:30 p.m. 

John Kelly vs. Southern Miss formidable run defense: The Tennessee running back returns with a vengeance after being suspended for last week’s game. He looks to break 100 yards for the first time since a 101-yard game on Sept. 23.  The Golden Eagles’ defense had been good against the run until last week when it yielded 209 yards on the ground to UAB.

LSU (6-2, 3-1) at Alabama (8-0, 5-0)

8 p.m.

Tigers’ jet sweep vs. Alabama LBs/CBs: How will Alabama respond to being supplanted from its perch atop the college football rankings? The jet sweep has been an effective play for LSU and must be against Alabama because the Tigers won’t be pounding the ball against the nation’s top defense against the rush. Taking away that play would go a long way for Alabama in smothering the Tigers’ offense.
