The fact that Callahan's agent spoke this way, especially the "stupid" comment indicates that the agent, who is probably rarely in Nebraska, hears a lot of negative about Nebraska from Callahan.
Also, based on calls to the post game call-in show, seems like Callahan was not a happy guy when he walked off the field and into the tunnel tonight. Many people think he had an arrogant attitude and was giving a big "F you" to the fans.
A head coach like that is not good for any program, especially Nebraska.
