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.

11. Bo Wallace, Ole Miss, 52.0 (16-31, 235 yards, 2 INT) — Wallace was miserable during the Rebels’ third loss in four games, registering his lowest adjusted QBR (20.8) of the season after a mistake-filled outing featured two interceptions (one returned for a touchdown) and two lost fumbles. If there was ever a ‘Bad Bo’ this season, his forgettable night in Arkansas was it.

10. Johnny McCrary, Vanderbilt, 60.8 (15-31, 161 yards, INT) — The second quarterback of an offense that was shutout in Week 13, McCrary had little time to work in an oft-collapsing pocket at Mississippi State. He found tight end Davis Dudchock for three first-down receptions and that was all worth mentioning in terms of Vandy highlights in the passing game.

9. Joshua Dobbs, Tennessee, 78.3 (24-37, 195 yards, TD/INT) — The sophomore’s other-worldly two-game stretch came to an end against a defensive front seven that caused constant disruption in Knoxville. The dual-threat was limited to just 13 yards on 17 carries and rarely got loose outside of the pocket.

8. Nick Marshall, Auburn, 80.0 (11-18, 171 yards, TD/INT) — Held to negative rushing yards for the first time in his career, Marshall struggled against a Samford defense that did a great job staying at home and focusing on gap control against Auburn’s zone read.

7. Dylan Thompson, South Carolina, 84.5 (10-17, 237 yards, TD/INT; TD reception) — It was an unfortunate mediocre performance in the final home game for the fifth-year senior who moved to within seven touchdown passes of tying Steve Tanneyhill’s single-season program record (29). Thompson had two would-be completions dropped by Buster Anderson and was picked off on a bad throw over the middle. He did catch a touchdown pass which improves his rating this week.

6. Brandon Allen, Arkansas, 85.8 (5-10, 87 yards, TD) — Allen wasn’t needed much during the Razorbacks’ 30-0 win over Ole Miss after he tossed a nice touchdown pass down the seam to Keon Hatcher on his team’s first possession.

5. Maty Mauk, Mizzou, 87.0 (12-25, 230 yards, 2 TD) — The Tigers have learned to live with Mauk’s low completion percentage and are still winning thanks to great decision-making with the football. Mauk’s thrown seven touchdown passes and just one interception over his last four SEC starts after going scoreless and five picks over his first three.

4. Blake Sims, Alabama, 88.5 (17-25, 222 yards, 2 TD/INT) — In a half of play, Sims was effective and helped the Crimson Tide move the football to the tune of 38 points. His lone pick came on an overthrown deep ball that was tracked down in the back of the end zone by a Western Carolina defensive back. In relief, Jacob Coker completed 12-of-18 passes for 115 yards and a score.

3. Dak Prescott, Mississippi State, 96.7 (16-21, 193 yards, 3 TD; 30 yards rushing, TD) — Prescott bounced back from a forgettable three-interception game at Alabama to lead a 51-point beatdown of Vanderbilt, accounting for at least four touchdowns for the fourth time this season. His completion percentage of 76.2 was his second-best in SEC play.

2. Jeff Driskel, Florida, 97.0 (9-11, 164 yards, 3 TD; rush TD) — In relief of Treon Harris, Driskel was nearly perfect with command in the pocket against a weak Eastern Kentucky secondary, accounting for three touchdown passes and a touchdown rush. And he was turnover-free.

1. Hutson Mason, Georgia, 98.0 (10-12, 187 yards, 3 TD) — Leading an offense that faced just nine third downs all afternoon, Mason posted another efficient passing outing at home with a 99.4 QBR after completing 10-of-12 passes for 187 yards and three scores. Mason’s last interception came against Vanderbilt in Athens on Oct. 4. He’s responsible for 14 touchdowns since.
