I have never been a fan of defensive guys as head coaches but this thought is even stronger for me now in today's age of football. Offense wins games now simply because offenses are so much more complex and the rules of football favor offenses now. Look at Saban one of the greatest defensive coaches in history and even he has given up on the idea of trying to hold teams under X amount of points. If you go the defensive route the OC has to be a homerun hire and I think that is more challenging than hiring on offensive guy as HC and bringing in a DC that has a competitive, above average defense that is going to give the offense a chance.....which we don't have right now.
