A total of 45 students were assigned to teams through the Draft of 2022 from a pool of approximately 120 eligible athletes. The first five picks of the first round were: 1. Kiwanis Kolts (Tomás Carles), 2. Balboa Dragons (Gustavo Layne), 3. La Salle Spartans (Lucas Montenegro), 4. AIP Owls (Denis Espinoza), and 5. Brader Raiders (Shawn Leal).
