as much has been in the media regardnig Groce and Levert, JG has always takent the high ground and not commented on the subject. My gut and listening between the lines I have always felt our former HC kept hands off out of respect for Ohio even when it meant he would be facing Caris for 4 years.
I think in most cases it is a coach by coach situation. If you really look at a coach and his general behaviour/character over the years it is pretty predictable the ones who are going to act honorably and those who are going to disregard any gentlemanly observation of unwritten and generally accepted behaviour.
