A few sour grapes got squashed:

McDermott says he thinks his coaching was the reason that Johnson decided to leave. "You know my job, and I'm not going to appologize for what I do and how I do it -- is to help young people grow on and off the court. And sometimes that involves doing things and saying things that may not be popular with and 18 or 19-year-old. I mean it's no different from my role as a parent. Sometimes you have to put your foot down and they don't understand it, and they don't get it, and you hope they don't take it personal," McDermott say [sic]

McDermott says Johnson didn't handle the coaching well. He says in his opinion, Johnson took some of his coaching personal and could not get passed it. [sic]
