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. Jeff Driskel, Florida, 50.0 (11-23, 59 yards, 3 INT) — It looks like Driskel’s play under center is going to dictate Will Muschamp’s job status at the end of the season with the news of today’s Treon Harris suspension. Harris relieved Driskel in the fourth quarter after a miserable performance from the starter and directed two scoring drives to lead the Gators to a 10-9 win. Driskel’s thrown six interceptions in his last 94 attempts.

11. Brandon Harris + Anthony Jennings, LSU, 52.6 (8-24, 124 yards) — Handcuffed at the position, there’s not much Les Miles can do besides go with the hot hand right now at quarterback. Neither passer performed well Saturday night at Auburn with two completions spanning 92 yards (much of the total production).

10. Dylan Thompson, South Carolina, 55.1 (23-37, 218 yards, TD/3 INT) — Thompson’s career-worst outing may have kicked off a midseason tailspin for the Gamecocks who appear to be the nation’s most overrated team through six games. His first interception came in the red zone, his second was returned for the game-winning touchdown and his third ended the game at Kentucky. The Wildcats picked off three passes all of last season and matched that total Saturday night.

9. Wade Freebeck, Vanderbilt, 58.5 (9-18, 100 yards) — Freebeck played turnover-free at Georgia, a mini-win considering the Commodores’ season-long struggles under center. When he was replaced by Stephen Rivers, the LSU transfer promptly tossed a pick-six after reading the play call off his wristband upside down.

8. Justin Worley, Tennessee, 62.5 (26-39, 205 yards, 2 INT) — The senior regressed significantly after his best outing of the season at Georgia with a stinker against the Gators. Oft-pressured without a solid pocket, Worley’s decision-making was often questioned. Despite the offense as a whole struggling throughout the day, Worley still had a chance to get the Vols into field goal range late and tossed the game-sealing interception.

7. Blake Sims, Alabama, 76.8 (19-31, 228 yards, INT; rushing TD) — Outside of a well-called naked bootleg for a touchdown in the second quarter, there wasn’t much Sims could do against college football’s stingiest secondary. His top receiving threat, Amari Cooper, was blanketed after the catch and openings down the field weren’t available. His lone interception came on a well-placed heave to O.J. Howard late, but Senquez Golson’s acrobatic catch in the back of the end zone sealed Alabama’s fate.

6. Hutson Mason, Georgia, 79.0 (11-17, 121 yards, 2 TD/INT) — Average. That’s the general consensus on Georgia’s passing game this season and Saturday was no different against Vanderbilt. Mason hooked up with Chris Conley twice for touchdowns, one a 44-yarder, but that was it as far as big plays are concerned. The Bulldogs fed Todd gurley throughout. Expect Brice Ramsey to continue to receive playing time as the season progresses.

5. Kenny Hill, Texas A&M, 84.3 (37-62, 365 yards, 4 TD/3 INT) — For the second straight week, Hill wasn’t as sharp as we have come to expect out of the sophomore and this time, was picked off a season-high three times by Mississippi State. Much of his yardage came when the game was out of reach, a product of the Aggies being forced to throw the football nearly every play (see Arkansas, last week). His Heisman campaign took a sharp turn with a second straight so-so outing.

4. Patrick Towles, Kentucky, 88.1 (20-29, 208 yards, TD) — Towles has been the unsung hero to an extent for the Wildcats (4-1) this season and made the necessary plays against South Carolina to gash one of the league’s worst units against the pass. His 48-yard touchdown strike to Ryan Timmons on third down in the third quarter gave Kentucky its first lead and Towles let Jojo Kemp handle the burden the rest of the way.

3. Nick Marshall, Auburn, 95.6 (14-22, 207 yards, 2 TD; 119 yards rushing, 2 TD) — All the clamoring about second-teamer Jeremy Johnson has finally subsided after Marshall’s second consecutive strong showing. His 96.4 adjusted QBR against LSU was a career-best when he’s thrown at least 20 passes and 119 rushing yards puts him second to only Dak Prescott in the SEC for quarterbacks. Marshall’s back in the Heisman talks and could separate himself with highlight-worthy performance this weekend against Mississippi State.

2. Bo Wallace, Ole Miss, 96.5 (18-31, 251 yards, 3 TD) — Credit this senior quarterback for proving doubters wrong and playing mistake-free football against the top-ranked team in the country. Wallace discovered the clutch gene Saturday afternoon on the grand stage, throwing two touchdown passes in the final six minutes to lead the Rebels to one of their biggest wins in program history, their first over a No. 1 team.

1. Dak Prescott, Mississippi State, 97.9 (20-26, 268 yards, 2 TD; 77 yards rushing, 2 TD) — Arguably Prescott’s best outing of the season came when the Bulldogs needed it most against previously unbeaten Texas A&M. He was responsible for a weekend-high five touchdowns and put the ball where it needed to be against an underwhelming Aggies secondary. Prescott led his team on four touchdown drives in the first half after Texas A&M opened the game on 69-yard march in just two minutes.
