I will go out on a limb here as a local high school coach and give you my hypothesis. Richard grew up around his dad of course, who is one of the most prominent coaches in the history of college basketball. Personality, success, prominence...he had it all. I get the impression that Rick Pitino is a great relationship builder. He then lived off of those relationships. I also always got the impression that Richard tried to act like he had already built relationships with the local coaches, but never really did, yet tried to act like there was a relationship there. He tried to jump to be like his dad, without doing the things his dad did to build relationships to be successful.
We invited him to the coaching clinics, he always showed up, always was pleasant and a nice guy, but the whole thing just felt superficial. Nothing bad, nothing that was rude or disrespectful, but also just not a true relationship builder. In addition he is not one of those coaches who commands respect. Because of his name and position, he expected it, which is fair, but again, it was all a bit superficial. I don't remember one local coach who spoke up for Richard when he was let go (not saying they did not, but I did not see it). I also did not see anyone who seemed happy he was gone....again, just kind of blah and indifferent.
