I like numbers. Even when you look at the whole "Bama hasn't played anyone", numbers give you a peek into what they have done with what they had to face.
Currently, against Bama, our opponents are averaging:
16/37 passing (43%) for 201 yards, 1.67 INT, and 1.33 TD per game.
In their games against other opponents these same teams have accomplished:
20/30 passing (66%) for 292 yards, .67 INT, and 2.5 TD per game.
That means Bama is averaging allowing 20% fewer completions, 33% fewer yards, and 47% fewer points per game with 149% more interceptions interceptions while facing 20% more pass attempts.
For rushing, against Bama:
31 rushes for 101 yards and 0 TD
Against other competition:
37 rushes for 195 yards and 2 TD
So Bama is facing 20% fewer attempts and allowing almost 50% of the yards with no scores.
Now, these stats do hide a few things.
We struggled against Louisville's passing game. They only average 126 yards per game elsewhere but passed for 252 against Bama. They also passed about twice as many times as in any other game so that probably skewed those numbers.
Arky State put up decent numbers passing against us, but we held them way below their average and much of that did come later. They also passed 51 times in the game, which means they averaged very little per attempt.
Ole Miss skews our average heavily. They average 68% completion for 407 per game outside Bama but against Bama they could only come up with 32% complete for 133.
My take away is that we have an effective run defense and our pass defense is getting better every game.
