Michigan State is undefeated this season, but they have yet to play a road game in 2025.

Additionally, the Trojans’ robust offensive ranking and home-field success further reinforce this outlook.

Given these factors, USC is likely to cover the 17.5-point spread against Michigan State. The Trojans’ balanced offensive attack and solid defense should guide them to a comfortable victory in Los Angeles Memorial Coliseum, with a projected final score of USC 45 – Michigan State 20.
