I don't know who plays for all of the schools, but I do know a future Dukie plays for one of them. Marshall Plumlee's Christ School will be playing in the Shavlik Randolph bracket.

Q "Why do you like Duke, you didn't even go there." A "Because my art school didn't have a basketball team."
T.J. Warren played for Riverside last year. But I think I read somewhere that he transferred to Word of God.
