I don't expect CJP to answer to the fans, that is not his job. I do expect that he has to answer to the AD and President. Given the public responses from both the AD and President and the fact there was a month between when GT was aware of the violations and when they went public, I expect there were serious conversations between those 3 during that time period.
Given both the public statements by GT and the lack of additional penalties by the NCAA, it appears both are satisfied with his explanations.
It was clearly bad decisions by Pastner, hopefully he has learned a valuable lesson.
