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. Treon Harris, Florida, 62.0 (3-6, 27 yards; 31 yards rushing) — We expected to make an impact in Saturday’s game vs. Georgia, but the Gators didn’t need his arm. Florida rushed for a season-high 418 yards during a light day for the true freshman quarterback.

11. Kyle Allen, Texas A&M, 65.5 (13-28, 101 yards, TD/INT) — A noticeably different Allen-led Texas A&M offense struggled without suspended Kenny Hill, going scoreless in the second half of a five-point over Louisiana-Monroe. Allen completed less than 50 percent of his passes, struggled down the field and rarely threatened the opposition from the pocket.

10. Brandon Allen, Arkansas, 67.5 (22-43, 238 yards, INT) — Allen struggled to find openings against Mississippi State’s oft-criticized and tossed an interception. When the Razorbacks’ run game is handled and Allen has to perform, the offense has struggled this season.

9. Patrick Towles, Kentucky, 70.0 (19-36, 158 yards, TD/INT) — Towles’ worst outing of the season came a week after his best, a 466-yard masterpiece vs. Mississippi State. During Saturday’s loss at Mizzou, Towles never got going against the Tigers’ relentless pressure and established a season-low raw QBR of 5.8.

8. Hutson Mason, Georgia, 80.5 (26-41, 319 yards, TD) — Mason’s career-high passing outing against Florida didn’t include many big plays and much of the total yardage came with the Bulldogs trailing by several touchdowns. Georgia’s been a run-first offense throughout the season and when Mason’s forced to perform, it usually plays to the opposition’s strengths.

7. Dak Prescott, Mississippi State, 83.1 (18-27, 331 yards, TD, 2 INT; 61 yards rushing) — It was definitely wasn’t a Dak-like performance against Arkansas, but Prescott set a new career-high for passing yards and did manage 61 yards rushing. His lone touchdown pass on a broken coverage won the game for the Bulldogs in the fourth quarter.

6. Maty Mauk, Mizzou, 88.5 (18-33, 164 yards, 2 TD; 75 yards rushing) — It’s not pretty, but Mauk continues to win and that’s all that matters during the second half of the season. The Tigers moved into first place in the SEC East after a win over Kentucky and Georgia’s loss to Florida. Both of Mauk’s touchdown passes went to Bud Sasser and he played mistake free. Seventy-five yards rushing and a couple first downs also helped the Mizzou offense.

5. Dylan Thompson, South Carolina, 86.7 (20-32, 347 yards, 2 TD/INT) — The leader of an offensive attack that managed over 600 yards against Tennessee, Thompson’s best throw came in the second half on an 85-yard connection with Pharoh Cooper for a touchdown. His first-quarter interception came on a lofted pass in the shadow on his own end zone on a broken route. Tennessee scored a few plays later.

4. Bo Wallace, Ole Miss, 91.8 (28-40, 341 yards, 2 TD; 56 yards rushing, TD) — This senior quarterback bounced back from a subpar performance at LSU with three total touchdowns, but did lose a crucial fumble inside the 5. He nearly tossed a third touchdown pass to win the game late in the fourth, but Laquon Treadwell fumbled at the goal line after being tackled from behind.

3. Nick Marshall, Auburn, 93.7 (15-22, 254 yards, 2 TD/INT; 50 yards rushing, 2 TD) — Effective throughout Saturday night’s win over Ole Miss, Marshall accounted for four total touchdowns for the second straight game and posted a high completion percentage against the SEC’s top secondary. He pushed his way back in the SEC Heisman race as well.

2. Johnny McCrary, Vanderbilt, 98.3 (20-29, 281 yards, 5 TD) — A Vanderbilt quarterback in the No. 2 top spot? It happened this week after McCrary’s stellar outing against Old Dominion on Saturday, a five-touchdown stat line that helped the Commodores win for the third time this season. McCrary showed accuracy from the pocket and on the run, completing a season-best 20-of-29 passes.

1. Joshua Dobbs, Tennessee, 97.9 (23-40, 301 yards, 2 TD/INT; 166 yards rushing, 3 TD) — This national player of the week candidate shredded South Carolina’s defense for an incredible 467 yards of offense and five touchdowns, lifting Tennessee to an overtime win at South Carolina. When the pocket collapsed and on zone read keepers, Dobbs made it happen with his feet, dissecting the SEC East’s worst defense against the run with 166 yards on the ground.
