There's a misconception that has never really been dispelled for one reason or another that Bill Self develops bigs. I will agree that he gets them drafted, but they never really go anywhere in the NBA. Arguably his best bigs have been Brian Cook (at Illinois), Darrell Arthur, Cole Aldrich, Joel Embiid, Thomas Robinson, Wayne Simien, and the Morris twins (average draft position of #16) . Of those guys, no ones really been an NBA "star".
As for Cal, he's only coached Marcus Camby, DeMarcus Cousins, Patrick Patterson, Terrence Jones, Anthony Davis, Nerlens Noel, and Julius Randle, (average draft position of #7) (*** soon to add Willie Cauley-Stein, Karl Anthony Towns, Trey Lyles, and Dakari Johnson***).
Cal should be the one known for developing bigs, and not Bill Self.
