USC versus Indiana is a season-defining game for both teams. The defending champion Hoosiers might miss the College Football Playoff if they lose. USC definitely won't make the playoff if it falls short, and fresh criticism will greet embattled coach Lincoln Riley. In a very high-stakes game, the biggest and most central key is a natural point of interest. Our view on this topic is clear.
The USC offensive line versus the Indiana defensive line is by far the most important position-group battle on the field in Bloomington. Indiana's quarterback situation is a mess, and Indiana's special teams are shaky. Indiana's obvious strength, the core of the team and the reason the Hoosiers have lost only once this season despite some terrible offensive performances,
is its defensive line. Many aspects of the 2026 Indiana team are noticeably worse than the 2025 national championship squad, but the defensive line isn't one of them. This is the heartbeat and backbone of the Hoosiers.
Mindful of how great USC looked when the offensive line thrived against Ohio State, and mindful of how bad USC looked when the offensive line no-showed at Wisconsin, it stands to reason that the way the Trojans' offensive front performs will define how this Indiana game unfolds. Either USC scores 27 - which a sputtering Indiana offense will struggle to do - or USC scores just 10 or 13 points, giving Indiana more than enough margin for error on offense.
Many aspects of this game matter, but none are likely to matter more than the USC O-line against the Indiana D-line.
