Fresh off an impressive road victory over a Power 4 opponent, Auburn returns to the Plains on Saturday to face Ball State in its home opener.The Tigers (1-0) got an extra day to prepare for the Cardinals (0-1) thanks to their 38-24 win at Baylor coming last Friday. Even with a win over a Big 12 team, Auburn coach Hugh Freeze told reporters earlier this week he still found areas where his team needs to improve.Most notably, the Tigers’ secondary allowed the Bears to amass 419 yards passing with three touchdowns and no interceptions. Baylor also had seven passing plays that went for 20 yards or more.Baylor outgained Auburn 483-415, but the Tigers’ defense was able to force turnovers on downs three times in the contest, including twice in the red zone.”I thought our defensive line controlled the line of scrimmage, and without that, we could have been in for a long night,” Freeze said.The Tigers’ ground game served as the foundation for the offense, gaining 307 yards on 52 carries. Dual-threat quarterback Jackson Arnold along with running backs Damari Alston and Jeremiah Cobb all had 16 carries apiece.
