Indiana returns from its bye week preparing for one of its biggest challenges of the season as USC travels to Bloomington on Saturday. Curt Cignetti's Hoosiers are coming off a 23-16 overtime victory over Minnesota, but questions remain about an offense that has struggled to find consistency in recent weeks.

USC enters the matchup at 7-2 following an impressive victory over Ohio State, while Indiana is favored by 7.5 points. With the Hoosiers still chasing a Big Ten championship and a College Football Playoff berth, Saturday's showdown could have major implications.

1. Who will start at quarterback for Indiana: Josh Hoover or Grant Wilson?

This is easily the biggest storyline surrounding Indiana. Hoover started against Minnesota but was replaced by Wilson at halftime, and the Hoosiers ultimately escaped with an overtime victory. With an entire bye week to evaluate both quarterbacks, Cignetti has a significant decision to make. Will he stick with the more experienced Hoover, or has Wilson done enough to earn his first start?

2. Can Indiana's defense slow down Lincoln Riley's explosive offense?

USC presents one of the most difficult offensive challenges Indiana has faced this season. Lincoln Riley's reputation for developing quarterbacks and creating explosive plays is well established, and the Trojans are coming off an impressive victory over Ohio State. Can Indiana's defense, which ranks among the nation's best against the run, force USC into uncomfortable situations and prevent big plays?

3. Will Indiana's pass rush be the difference against USC?

Indiana's defensive front has been one of its biggest strengths, with players like Tobi Osunsanmi, Stephen Daley, Mario Landino and Tyrique Tucker creating problems for opposing offenses. Against a USC team that wants to throw the football and create explosive plays, consistent pressure could be critical. Can the Hoosiers disrupt the Trojans' timing without sacrificing coverage downfield?

4. Will Indiana's rushing attack take pressure off its quarterback?

Regardless of who starts at quarterback, Indiana needs more consistency from its running game. Lee Beebe Jr. and Turbo Richard give the Hoosiers two great options in the backfield, but establishing a dependable ground attack has become increasingly important. Can Indiana control the line of scrimmage, stay ahead of the chains and avoid putting its quarterback in obvious passing situations?

5. Will the bye week give Indiana a significant advantage?

Indiana enters Saturday's matchup with an extra week to rest, evaluate its quarterback situation and prepare for USC. Meanwhile, the Trojans are coming off an emotional victory over Ohio State. Can Cignetti capitalize on the additional preparation time and have his team looking sharper, healthier and more disciplined than it did before the break?
