Each week, SDS will break down SEC quarterback play by team using our own power index system, a numeral rating developed using all passer-related statistics and efficiency totals. Quarterbacks will be graded based on the previous game’s performance only from QBR, to completion percentage to third-down conversions and placed in order from average to elite.

12. Anthony Jennings, LSU, 60.5 (12-22, 87 yards) — Harassed throughout by a fierce Arkansas front seven, Jennings never found a rhythm against the Razorbacks as the Tigers were blanked for the first time since the 2011 BCS National Championship Game. By game’s end, fans were calling for freshman Brandon Harris under center.

11. Nick Marshall, Auburn, 65.4 (11-23, 112 yards, INT; 41 yards rushing) — Marshall picked a bad time for his worst game of the season, Auburn’s third loss in its last five games. He was kept out of the end zone for the first time this fall and had a season-low completion percentage of 47.8. The Tigers struggled on offense after a opening possession touchdown drive.

10. Patrick Towles, Kentucky, 67.4 (13-25, 168 yards, INT; 29 yards rushing, TD) — In the midst of a five-game slide, Towles hasn’t had much to work with on offense and played through an ankle injury during a blowout loss in Knoxville. The Vols picked him off and held Towles out of the end zone through the air for only the second time this season.

9. Maty Mauk, Mizzou, 79.0 (23-40, 252 yards, TD/INT) — Mauk was average at Texas A&M from a passing standpoint, but he facilitated an offense that erupted for nearly 600 yards against one of the SEC’s most embarrassing defenses. With Mauk at quarterback, the Tigers remained in control of their own destiny in the East.

8. Dak Prescott, Mississippi State, 79.8 (27-48, 290 yards 2 TD/3 INT; 82 yards rushing) — The Bulldogs were able to run 88 plays at Alabama, but the lack of a 60-40 run, pass edge damaged Mississippi State’s win probability. Prescott threw a career-high 48 passes — not a winning formula for Dan Mullen’s offense thanks to three turnovers. Prescott’s 30 or more passes in five career games and the numbers — six touchdowns, nine interceptions — aren’t impressive.

7. Treon Harris, Florida, 80.2 (5-11, 60 yards, TD; 111 yards rushing) — The freshman injured his hand in the first half, limiting the Gators’ ability to throw the football the rest of the way. In a one-dimensional offense, Harris picked up a career-best 111 yards on the ground on 20 carries, but lost a costly fumble in the third quarter.

6. Dylan Thompson, South Carolina, 83.0 (22-41, 206 yards; TD rush) — It wasn’t Thompson’s best outing by any stretch, but he avoided mistakes and scored the game-winning overtime touchdown on a zone read keeper in the Swamp. The fifth-year senior missed several throws to the boundary and was shaky from the pocket. His late scramble and completion to Mike Davis in regulation set up the game-tying score.

5. Brandon Allen, Arkansas, 85.5 (16-27, 169 yards) — In the prototypical game-manager role, Allen found success on third down and kept the football out of the hands of LSU’s athletic secondary. A.J. Derby and Hunter Henry were among his favorite targets during the Razorbacks’ first SEC win in 18 games.

4. Hutson Mason, Georgia, 89.2 (10-19, 124 yards, TD) — Thanks to a pair of 100-yard outings and three total touchdowns from Todd Gurley and Nick Chubb, Mason didn’t have to test Auburn’s secondary during Saturday night’s 27-point blowout. His completion percentage was lacking, but a red zone touchdown pass to Malcolm Mitchell put the Bulldogs on the scoreboard and kick-started the rout.

3. Kyle Allen, Texas A&M, 91.5 (24-35, 237 yards, 3 TD/INT) — In his third start, the freshman passer posted a season-best 24 completions in 35 attempts and tossed his 9th, 10th and 11th touchdown passes of the season. The Aggies suffered a letdown post-Auburn, but it wasn’t Allen’s fault.

2. Blake Sims, Alabama, 94.0 (19-31, 211 yards, TD) — Steady performances are becoming common for Sims, arguably the SEC’s most underrated player and in the conversation for the league’s best quarterback this season. Over his last five starts, Sims has accounted for 12 touchdowns without a turnovers — the definition of efficiency.

1. Joshua Dobbs, Tennessee, 96.8 (19-27, 297 yards, 3 TD; 48 yards rushing, TD) — Dobbs continued his assault on the SEC East with another stellar outing, this time carving up Kentucky’s defense for 345 total yards and four touchdowns. Tennessee’s problems up front have been disguised thus far in both of Dobbs’ starts thanks to his escapability.
