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 from completion percentage to third-down conversions and placed in order from average to elite.

13. Stephen Rivers, Vanderbilt 54.5 (6-25, 60 yards, INT) — At the bottom of the SEC for the second consecutive week, Vanderbilt’s quarterback play has been horrendous thus far — 0 touchdowns, 4 INT. Derek Mason started Rivers against Ole Miss and the LSU transfer was ineffective from the pocket and tossed a pick six.

12. Nick Marshall, Auburn 75.4 (10-19, 101 yards, TD) — There’s no quarterback controversy for the Tigers, but Marshall’s rusty a bit through the air. He did have 103 of his team’s 358 rushing yards and was effective on third down. As long as his arm’s not a liability or turnover-prone, Gus Malzahn’ can with an underwhelming passing performance such as this.

11. Patrick Towles, Kentucky 79.8 (17-31, 170 yards, TD) — A considerable drop-off from the second-rated slot after Week 1, Towles managed the game for the Wildcats but didn’t do anything spectacular. His completion percentage (69.0 to 54.8) dropped considerably against a better defense, something to watch entering SEC play at Florida this weekend.

10. Dylan Thompson, South Carolina 82.5 (25-38, 266 yards, TD/INT) — Thompson settled down after a shaky start and completed 11 of his first 12 passes in the second half including six in a seven-play span during a third-quarter touchdown drive. Thompson’s fifth touchdown pass of the season to a wide open K.J. Brent in the corner of the end zone gave the Gamecocks a 27-16 lead.

9. Justin Worley, Tennessee 84.9 (22-38, 247 yards, 2 TD/INT) — The Vols’ senior quarterback had a few errant throws on third down, but had another efficient, multi-touchdown outing. Two darts to a well-covered Marquez North went for scores.

8.  Bo Wallace, Ole Miss 86.4 (23-30, 320 yards, TD) — Wallace took advantage of Vanderbilt’s vanilla coverages to complete 76.7 percent of his throws for another 300-plus yard performance. Most importantly, Wallace avoided costly mistakes and delivered the football to the proper receiver (often down the seam).

7. Dak Prescott, Mississippi State 89.9 (12-25, 211 yards, 4 TD/INT) — Prescott, not Kenny Hill, leads the SEC in touchdown passes (8) and total touchdowns (9) after his second straight start with four touchdown passes against UAB. He also added 118 yards rushing, a dimension few quarterbacks in this league possess.

6. Anthony Jennings, LSU 91.4 (7-13, 188 yards, 3 TD) — Behind a strong running game, Jennings only attempted 13 passes but he connected three times for scores with sophomore standout Travin Dural. Jennings has touch and can throw the deep ball, but outside of last year’s win over Arkansas, we’ve yet to see him in a situation where the game’s outcome is on his shoulders.

5. Maty Mauk, Mizzou 91.5 (21-32, 325 yards, 5 TD/2 INT) — Mauk made two mistakes under pressure but played well otherwise, throwing for 325 yards and a career-high five touchdowns during the Tigers’ blowout win at Toledo.

3b. Kenny Hill, Texas A&M 96.5 (17-26, 283 yards, 4 TD) — Proving his first start wasn’t a fluke, Hill dissected Lamar with four touchdown passes by Texas A&M second possession of the second half.

3a. Jeff Driskel + Treon Harris, Florida, 96.5 (33-47, 396 yards, 3 TD) — With nine minutes to play in the third quarter Saturday, Driskel had already set a career-high for attempts in Kurt Roper’s first game as Florida’s offensive coordinator. He didn’t disappoint, throwing for 248 yards and a score. Harris entered the game in the third quarter and promptly burned the Eastern Michigan secondary with a pair of long touchdowns.

2. Blake Sims + Jacob Coker, Alabama, 96.9 (27-38, 430 yards, 3 TD) — Lane Kiffin called a great game and the Crimson Tide quarterbacks took advantage of safe throws to tally 430 yards through the air .

1. Brandon Allen, 97.7 (4-5, 117 yards, 4 TD) — Virtually flawless against Nicholls State, Allen’s only incompletion was an overthrow near the sideline. His other four passes covered 117 yards and each went for touchdowns.
