This is what I think about all these "insiders" and "sources" right now.
It is fairly obvious that nobody besides Glass (and possibly McRobbie) knows what Glass is planning/thinking.
Crean would be a hell of a poker player...not. Vague response to the question. I interpret his response as more of an avoidance than a position of stance.
At this point I feel that Glass would not only lose respect of the fanbase, but coaching circles as well. If he was going to endorse Crean, it would have already happened.
