I have no insider information. Maybe KF hasn't hired a formal search firm, but his agent calls Chryst's agent and strikes up the conversation. Or you have a common coaching connection.
Look, maybe with Philben and Chryst he knows them well enough to cold call them, but usually this stuff is done through third parties. Either way, I doubt KF is calling up multiple candidates, giving them formal job offers, and then being turned down. Its just not the way you hire for high level positions like this.
Think of it this way. In high school, guys would rarely walk up to a girl cold and ask her out. You have your friend check with her friends and then you chat her up and see if the right vibe is there and then only if it is clear that she will say yes if you ask, do you ask. Why, so the entire school does not hear that you crashed and burned.
