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.

14. Patrick Towles, Kentucky, 65.2 (14-29, 176 yards, 2 INT) — It’s a good thing play-caller Neal Brown took another coaching job because Kentucky’s offense will likely have a new-look next season — and possibly a different quarterback. With sought-after redshirt freshman Drew Barker waiting on his opportunity, Towles has flatlined down the stretch, posting just two touchdown passes and five picks since starring against Mississippi St. on Oct. 25.

13. Patton Robinette, Vanderbilt, 66.1 (11-22, 131 yards, TD/2 INT) — Johnny McCrary started for the Commodores but this season’s original No. 1, Robinette, finished out the final 3.5 quarters. The quarterback position’s been rotational for Vandy, one of the reasons offensive coordinator Karl Dorrell was reportedly fired on Monday.

12. Treon Harris, Florida, 66.9 (13-32, 169 yards, TD/2 INT; 41 yards rushing) — Florida’s offense has struggled throughout the season and red zone deficiencies Tallahassee cost the Gators a shot at upsetting the unbeaten Seminoles. To Harris’ credit, tight end Tevin Westbrook was to blame for Terrance Smith’s 94-yard interception return for a touchdown in the first quarter. Westbrook tipped a well-thrown ball into the air that Smith snared for six. Looking to run in light of consistent pressure, Harris struggled from the pocket.

11. Bo Wallace, Ole Miss, 68.1 (13-30, 296 yards, INT; rush TD) — Fans will remember an emphatic offensive performance thanks to Jaylen Walton’s career outing, but Wallace didn’t deliver on his end, posting a quarterback rating of 34.2. Since posting three 300-yard games and 20 or more completions in all four starts to begin this season, Wallace has accomplished those feats just once the rest of the way against SEC competition.

10. Joshua Dobbs, Tennessee, 70.0 (11-20, 92 yards, 2 INT; 92 yards rushing, 2 TD) — Since all factors are taken into account when formulating our weekly quarterback ratings, Dobbs’ success on the ground at Vandy saves him here. As a passer, Dobbs was ineffective, throwing for a season-worst 92 yards with two interceptions and a couple others that were dropped by defensive backs.

9. Kyle Allen, Texas A&M, 75.5 (17-27, 144 yards, TD/INT) — The Aggies managed just 12 first downs on Thanksgiving against LSU, but had a chance to win the game with a touchdown drive late before Allen’s misguided interception. The true freshman threw one up for grabs thinking the Tigers had jumped offsides and it was picked off by Jalen Collins.

8. Dylan Thompson, South Carolina, 79.0 (21-39, 249 yards, TD; lost fumble) — Arguably his worst outing of the year, Thompson crumbled behind a faulty offensive line and was sacked five during a dismal performance at Clemson. He lost a fumble in the first half that led to a touchdown, struggled mechanically throughout and never found his usual rhythm as the SEC’s leader passer this season.

7. Anthony Jennings, LSU, 81.9 (12-21, 107 yards, TD/INT; 119 yards rushing) — Jennings provided his usual pedestrian numbers through the air, but it was his rushing prowess in the zone read that surprised the Texas A&M defense during the Tigers’ win. Jennings’ 119 yards rushing nearly tripled his previous high on the ground this season.

6. Hutson Mason, Georgia, 82.5 (18-28, 194 yards, TD/INT) — Mason was serviceable during Saturday’s loss to Georgia Tech, but his last throw in overtime was one he’d like to have back, an errant slant that was picked off to seal the Yellow Jackets’ 30-24 victory. Mason’s lone touchdown pass came on a 3-yard hookup with Malcolm Mitchell in tight coverage at the goal line.

5. Maty Mauk, Mizzou, 83.0 (25-42, 265 yards, TD/INT) — Mauk hooked up with Bud Sasser nine times for 127 yards and had several pinpoint throws to Jimmie Hunt (5 catches, 61 yards) that were dropped. Mauk seemed to let plays develop downfield more often from the pocket than he’s done all season, a benefit for the Tigers heading into Saturday’s SEC Championship Game against Alabama.

4. Dak Prescott, Mississippi State, 84.7  (22-37, 282 yards, TD; 48 yards rushing, TD) — The Bulldogs’ lowest offensive output of the season resulted in a crippling Egg Bowl loss, one that severely damaged Mississippi State’s Playoff chances. Prescott carried the football far too many times (24 attempts for 48 yards) and shouldered the offensive load.

3. Brandon Allen, Arkansas, 87.5 (13-30, 133 yards, 2 TD) — With Mizzou’s fierce front seven bottling up the Razorbacks’ rushing attack, Allen kept Arkansas in the game with two first-half touchdown passes despite playing through noticeable pain. The Tigers forced Bret Bielema’s team into being one-dimensional, often a recipe for success.

2. Blake Sims, Alabama, 91.9 (20-27, 312 yards, 4 TD/3 INT; TD rush) — A season-high three interceptions was an uncharacteristic total from Sims who appeared shaky early in his first Iron Bowl, but the senior playmaker settled down to lead a spirited second-half explosion and finished with 334 yards of total offense and five scores. Multiple touchdown bombs to Amari Cooper were fun to watch.

1. Nick Marshall, Auburn, 98.0 (27-43, 456 yards, 3 TD/INT; 49 yards rushing) — This senior went out with a bang in his final regular-season performance for the Tigers, throwing for a career-high and school record-setting 456 yards at Alabama. Marshall’s 68-yard strike to Sammie Coates in the second quarter was one of the best throws he’s made during his career.
