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 Karl-Anthony Towns/Jay Williams Pod, and in the final it was second-seed Colonia winning at top-seed St. Thomas Aquinas, 80-64.
