I think most people know that Ferentz has to go through the motions but in the end will be loyal and faithful and will put friendship over the health of the program and will select Parker. I doubt anyone else really had a chance (except his son perhaps). Bring in an outsider, interview him, and then tell everyone he is one of the top three. That way it looks like he is considering an outsider. His loyalty to his staff and best friends are far more important than the good of the Iowa program and always has been.
And that is why the program is on a downward spiral right now and he really doesn't seem to care to try to turn it around....
