I was lucky enough to live, for a few years, a few doors down from a former U of I head basketball coach (post-retirement), and he would never say a bad word about his successors (despite my prodding); when I asked him why, he said that that those who are not part of the team (e.g., administrators, fans and reporters) at any given time, only knew a very small percentage of what was really going on within the team (which is a lot more than basketball, as it involves academics, compliance, code of conduct guidelines, interpersonal situations such as family relationships and girlfriends, dealing with 18-23 year olds living away from home for the first time in general, and so forth), and since (in retirement) he was not fully appraised of the situation, it would be unfair to those on the team for him to comment with anything but supportive words.
It was his nice way of reminding me that we are just fans, and while we are important to the team, we operate on the far periphery of what is really happening. I try to keep that in mind when I post on message boards.
