IU's offense averaged 3.7 yards per rush and 8.4 yards per pass this season. Those yards per rush would have them in last place in the SEC behind Missouri's 3.8 yards per rush; however, the passing offense would have them tied for third in the SEC with Florida, and slightly ahead of Tennessee's 8.1.
IU's passing defense allows 7.1 yards per attempt which is equal to South Carolina. Their rush defense allows 3.9 yards per attempt which is worse than Tennessee's 3.7 yards per attempt.
So, the rush defense would be roughly middle-of-the-pack for the SEC.
