BYU kicks off their 2024 football season at home against Southern Illinois, with high expectations despite not having announced a starting quarterback. Jake Retzlaff is anticipated to start, given his strong performance in training camp. The Cougars aim to improve their offensive performance and capitalize on their home-field advantage, supported by a nearly sold-out Lavell Edwards Stadium. Southern Illinois, known for upsetting higher-division teams, should not be underestimated despite BYU's historical dominance over FCS opponents. The game is crucial for BYU, who had a challenging 2023 season, missing bowl eligibility and struggling in their Power Four transition. Success at home is essential, as BYU faces several ranked opponents in Provo this year.
