Texas A&M's defense has another serious challenge coming Saturday, and it starts with one of the most dangerous dual-threat quarterbacks in college football.

When the Aggies (4-4) travel to face No. 23 South Carolina (5-3), they'll encounter a Gamecocks offense averaging 464.1 yards and 36.9 points per game. That includes 217.5 rushing yards per contest, the 13th-best average nationally.

For Mike Elko and defensive coordinator Lyle Hemphill, slowing down five South Carolina playmakers could determine whether the Aggies can pull off an SEC road upset.

LaNorris Sellers | QB

Everything begins with Sellers, who's coming off a spectacular performance in South Carolina's 42-25 victory over Oklahoma.

Sellers completed 19 of 24 passes for 301 yards and three touchdowns while adding 96 rushing yards and two scores.

Through eight games, he's thrown for 1,849 yards and 16 touchdowns while rushing for another 603 yards and six scores.

He's also thrown seven interceptions, giving Texas A&M opportunities if it can force him into uncomfortable passing situations.

After throwing two interceptions against Oklahoma, Sellers recalled coach Shane Beamer delivering a rather blunt message.

"He said, 'Stop (expletive) turning the ball over,'" Sellers said.

Mazeo Bennett Jr. | WR

Bennett has become Sellers' most productive receiving target.

The sophomore leads South Carolina with 35 receptions for 431 yards and four touchdowns.

Against Oklahoma, Bennett caught four passes for 107 yards, including a 79-yard touchdown that demonstrated how quickly South Carolina can turn a broken play into six points.

Texas A&M's secondary can't afford to lose track of him when Sellers escapes the pocket.

Nyck Harbor | WR

At 6-5 with exceptional speed, Harbor presents a difficult matchup for almost any defensive back.

He has 20 catches for 334 yards and three touchdowns, averaging 16.7 yards per reception.

His combination of size and vertical speed makes him especially dangerous when South Carolina takes deep shots off play-action.

DJ Black | WR

Black might be the most explosive receiver on the roster.

He has 15 catches for 330 yards and two touchdowns, an impressive 22 yards per reception.

His 84-yard touchdown against Oklahoma was South Carolina's longest play of the season.

The Aggies must prevent Black from getting behind the secondary, particularly when Sellers extends plays.

Jabree Coleman | RB

Coleman's role suddenly becomes more important following a significant injury to starting running back Matt Fuller.

Fuller, who has rushed for 530 yards and five touchdowns, suffered a foot or lower-leg injury against Oklahoma that Beamer described as likely season-ending.

Coleman responded with 62 yards on 13 carries against the Sooners. He enters Saturday with 284 rushing yards and four touchdowns, averaging 6.5 yards per attempt.

For Texas A&M, the defensive formula is straightforward but difficult to execute.

The Aggies allow just 18.9 points and 315.6 yards per game, but South Carolina's combination of quarterback mobility, explosive receivers and a productive rushing attack presents a different kind of test.

Contain Sellers, eliminate explosive passing plays and force the Gamecocks into long third downs.

Do those three things, and Texas A&M gives itself a legitimate chance to leave Columbia with a much-needed victory.
