Note: In 2021, the GMC did not play a full tournament due to a shortened season as a result of COVID-19 restrictions. Instead, the GMC seeded “pods” of four teams each. The “top” pod was the Somogyi Family Pod – named after John Somogyi and his daughter, Kristen. The final saw second-seed St. Thomas Aquinas win at home over third-seed Monroe, 46-40.
