As the idea of Cowher coming here seems to be slowly diminishing (I will keep hope alive though), and I hear the debate for all of the canidates listed so far, I come back to something that was brought up awhile back, and that is Troy Calhoun.
Who is Troy Calhoun, he is currently the HC for the Air Forces Falcons. But going back through his career he started as a QB for the Falcons in the late eighties (arguably the best years of Air Force Falcon football), he moved on as a graduate assistant with Air Force working with Fisher DeBerry. In 1995 he moved on to Ohio University where he became their QB coach and offensive assistant, there his offenses ranked as some of the best in the nation. In 2001 he moved on to Wake Forest as an Offensive Coordinator, again the offense had a noted improvement once he came on board. In 2003 he moved to the Denver Broncos as a defensive assistant and ST assistant, later he would move to the offensive side of the ball with the Broncos. In 2006 he went with Gary Kubiak and the Texans as their QB coach and Offensive Coordinator, later that year he would be named as Head Coach of Air Force. His first year he took the Falcons back to a bowl game and was named the coach of the year in the MWC. This year he has again had succes with Air Force taking them to another bowl.
Things that I really like about Calhoun is he is a former QB (much like Shanahan and Kubiak) that got by more on his smarts than athletic ability. Being a former Air Force player you know he is exceptionally smart and focused. He is a born leader, being able to play QB at Air Force demands that. He has familiarity with the Broncos and their offensive staff and I am sure would keep the staff intact. He has shown he can take a team with limited athletes and make them into winners. He has been a HC and has had success. Now I will agree that he is not a defensive guru, but I am sure he is smart enough to know how to get someone in there that can transform the defense. And he will be fighting the stigma of a college coach, but, that being said, he excites me more than other college coaches that have been mentioned (Stoops) and I think he has as much qualifications as McDanials or Garrett on the offensive side of the ball. I would put his odds at slim at this point, but Bowlen at least needs to lob him a call and see.
