The Broncos, led by first-year head coach Clayton Bates, played their home games at University Arena in Kalamazoo, Michigan as members of the Mid-American Conference. In a season limited due to the ongoing COVID-19 pandemic, they finished the season 5–16, 4–12 in MAC play to finish in ninth place. As a result, they failed to qualify for the MAC tournament.[1]
