Reflecting back to the Tuberville era, I was always concerned with teams that were physical. Basically it was teams that could run the football and play well on run-defense. The following numbers support this theory...
From 2000-2008, Auburn compiled a record of 13-10 vs. FBS teams with a combination of a top-40 run-offense and top-40 run-defense. When Auburn faced teams that were not top-40 run-offense and top-40 run-defense, the Tigers went 42-5.
Looking at the years Gus Malzahn has coached the Auburn offense, the concern becomes teams that can pass the ball and play solid run-defense. Look at the data from 2009, 2010, 2011, 2013 and 2014...
When Auburn has faced teams with a top-40 pass-efficiency offense and top-40 run-defense combined, the Tigers are 6-6. When they have faced FBS opponents that were ranked below top-40 pass-offense and top-40 run-defense, Auburn is 22-4.
During this same time frame, Auburn is 10-7 vs. top-25 pass-efficiency offenses, allowing an average of 37 PPG. The Tigers are 32-5 vs. FBS opponents with a run-defense ranked below top-40, averaging 46 PPG.
Alabama is the only remaining opponent on this year's schedule that falls under top-40 pass-efficiency offense and top-40 run-defense. Alabama is currently No. 3 in PE-Offense and No. 2 vs. the run. Georgia is close to it, ranked No. 28 in PE-Offense and No. 49 vs. the run.
