Nice compilation. You will notice that all the successes for Kentucky were lottery picks and all the OADs were first round picks. Of the KU players, Shelby and Diallo were second round picks, Alexander was not drafted and Wiggins, Embiid, Henry and McLemore were the only lottery picks. Had McLemore not red shirted I am not sure he would have been an OAD.
No doubt tha Kentucky has had considerably more talent come through, most of its OAD were lottery picks that would have done well anywhere, so it is really not surprising that it has had more successful NBA players. Considering the talent differential, it is amazing how well KU has done sending players to the NBA.
