Only four SEC teams open their season against Power 5 conference foes this weekend: South Carolina, Auburn, Texas A&M and Alabama. So here’s a noteworthy player from each opponent of those squads for a quick scouting report as well as a few other key guys on the lower-level opponents.

Marquise Williams, QB, North Carolina: Williams will be one of the best-dual threat guys the Gamecocks will see this season, with USC facing the Tar Heels on Thursday in Charlotte. Last year as a junior, Williams set 18 UNC single-season or career records, including the single-season record of 3,856 total yards of offense. He also set single-season marks for most plays (621), touchdowns responsible for (34), rushing yards by a quarterback (788) and rushing touchdowns by a quarterback (13). “Quise” was one of just seven FBS players in the nation last year to lead his team in passing yards (3,068) and rushing yards (788). Williams owns UNC career records for rushing yards by a quarterback (1,510), rushing touchdowns by a quarterback (22). He surely will break the mark for career TDs responsible for as well.

Devonte Fields, DE/LB, Louisville: Fields was the Big 12 Defensive Player of the Year with 10 sacks at TCU two seasons ago. He was considered the No. 2 overall JUCO recruit for this year after spending the 2014 season at Trinity Valley Community College after being dismissed from TCU. The Cardinals are likely to use him both with his hand on the ground and at outside linebacker. Defensive coordinator Todd Grantham said it’s hasn’t been decided if Fields will start in the season opener against Auburn —  he is listed as a No. 1 linebacker currently — on Saturday in Atlanta but he’s going to play plenty regardless.

Corey Clement, RB, Wisconsin: The Badgers churn out some new running back every season or two and he almost always is one of the best in the nation behind that mammoth offensive line they cultivate up there in Madison. This year the baton goes to Clement, who backed up FBS leading rusher and Heisman Trophy finalist Melvin Gordon in 2014. Clement, a junior, has played in 26 games in two seasons, rushing for 1,496 yards and 16 touchdowns while averaging 7.0 yards per carry. Last year, Clement  combined with Gordon to set single-season FBS record for rushing yards by teammates at 3,536 yards. Clement is on the preseason Maxwell and Doak Walker Award watch lists. That Alabama front seven, considered perhaps the best in the nation, will have its hands full Saturday night in Arlington.

D.J. Foster, WR, Arizona State: Foster was one of the Pac-12’s best running backs last season. He led the Sun Devils with 1,081 rushing yards and nine touchdowns while also finishing second on the team in receiving with 62 catches, 688 yards and three touchdowns. He was the only player in the nation with more than 1,000 rushing yards and over 600 receiving yards. ASU was deep at running back but not receiver in 2015, so Foster has moved to wideout. But expect him all over the field against Texas A&M on Saturday in Houston.

Matt Johnson, QB, Bowling Green: The Falcons are two-time Mid-American Conference East champions. Could they pull an upset Saturday in Nashville against Tennessee? That depends largely on Johnson. He was hurt in the 2014 opener and missed the rest of the way. As a sophomore in 2013, Johnson completed 64.2 percent of his passes for 3,467 yards and 25 touchdowns. He was the MVP of the MAC Championship Game when he threw for 393 yards and five scores in an upset of ranked Northern Illinois.

Aaron Jones, RB, UTEP: Last year, Jones led the team with 1,321 rushing yards (fourth-best single-season total in program history), rushing scores (11), points (84), yards per game (110.1), attempts (242), total touchdowns (14) and all-purpose yards per game (134.5). He also led the Miners in receiving touchdowns (three), while ranking second in receptions (30) and yards (293). “We are going to ride Aaron Jones,” UTEP coach Sean Kugler said to the Associated Press this week. “He is going to catch the ball out of the backfield. He may line up in the slot. There’s no question that he’s our top playmaker.” No doubt he will be the focus of the Arkansas defense on Saturday afternoon.
