The process that was required to admit Dot was lengthy and arduous from what I understand. In the end, Khator had to sign off and she did after she did a lengthy review. From all accounts, Dot has been a model citizen and a leader both on and off the court during his time at Houston.
And there was an outcry from fans about admitting him. Quite a few raised objection to it as the athletic department has been relatively "clean" for some time. In the end, Dot did what was asked of him, and more, while at Houston and many of those same objectors now support him.
