Why do you guys say this kid is a DITR?
TAPPS (especially the larger schools) play quality ball, they just don't the same talent pool as larger public schools. Assuming that a TAPPS school like TCA Addison or Bishop Dunn have facilities roughly equivalent to a local public school like Hillcrest, etc., you would expect to see roughly the same number of D1-quality athletes per capita as any other school.
I would expect the TAPPS athlete might have inflated stats due to not facing the larger talent pool of competition, but I don't think it's fair to assume that they have lesser skills or abilities. I do think it is fair to assume that they are better prepared to deal with the academic rigors of their freshman year at SMU though.
