I played with GJ at Canton before he transferred to Gilmer. Our coach (his dad) was shot before our junior year, but he came back to coach us junior year. After that season, GJ transferred to Gilmer and his dad got a job at Baylor if I remember right. A receiver from Canton tried to transfer to Gilmer with him and got denied by the UIL. He played at a private school senior year and ended up winning a TAPPS state championship in 2006.
So, with the Demas situation, if he ends up going to a TAPPS school, he can still play even after losing UIL eligibility.
