Arizona AD Greg Byrne said Ed Rush's departure is a "good step" for the Pac-12 but the school otherwise is reacting in measured tones to the news that the conference's officials coordinator has resigned.

UA coach Sean Miller declined comment through a spokesman and Byrne told the Star only that he knew there was “deep concern” among Pac-12 school officials after Pac-12 commissioner Larry Scott confirmed that Rush made “inappropriate comments” while trying to prod officials into monitoring coaches more firmly during the Pac-12 Tournament.

Byrne declined additional comment but posted this tweet:

 

 

 

In his weekly newsletter Wednesday, Byrne first indicated UA expressed a concern to the Pac-12. He wrote:

“We are very concerned about the allegations and those concerns have been clearly expressed. President Hart has been very supportive and Sean (Miller) and I have been in constant communication throughout.”

Byrne said he received a phone call from Pac-12 commissioner Larry Scott with the news about Rush this afternoon but declined to say how the conversation went.

A message to Scott went unanswered and Pac-12 spokesman Erik Hardenbergh said he could not comment beyond what the conference said in its statement about Rush's departure.
