When I first saw that Sean Payton was planning to approach Bill Parcells to take over head coaching duties on an interim basis for the Saints, my knee-jerk reaction was an unequivocal "no". Upon further reflection, I believe Parcells may be the perfect choice for the Saints at this time.
First off, Bill Parcells offers a clean break from the Bountygate scandal. Having been retired as a head coach for a few years now, Parcells has no real ties to the Saints apart from the fact that he was Sean Payton's mentor. It might be nice to have a new face on the franchise for the 2012 season; an "outsider" if you will.
Secondly, promoting from within could lead to complications. If the Saints were to hire, for instance, Aaron Kromer, Pete Carmichael, or Steve Spagnuolo, and the Saints were to have a successful season, it's likely whoever had been installed as head coach would be hired away from us the following year. Furthermore, it could lead to a "coach controversy" which could split the fan base when Sean Payton's suspension expires. Such tension wouldn't exist with Parcells as head coach because he's already over 70 years old and it would be extremely unlikely he would want to coach for more than just the one season.
Additionally, Parcells has that intangible quality of gravitas. He has a truly magnetic personality and an ability to get the most out of his players. Moreover, he has a proven record of success, having led the New York Giants to two championsips, and having been the only head coach in NFL history to lead four different teams to the playoffs.
Therefore, for all of these reasons, I believe that Bill Parcells is the right man for the right time in the Crescent City.
