"However, that article did say that the Parcells coaching tree is among the teams incorporating it into their sets, and Prince does fall under that umbrella"
I wasn't aware they allowed minority relaitions interns in on gameplanning sessions in the NFL. 
Al Groh is the head coach at Virginia, and Prince was his offensive coordiantor. Also, if you are making fun of someone's position within an NFL franchise, it would be nice if you, yourself, held a job which was of equal or higher esteem than the job in question. Or, if you knew how to spell "relations." Just because you have never had "relations" with a female doesn't mean you couldn't at least consult a dictionary.
Parcells has had extraordinary success in grooming his assistant coaches for eventual head coaching positions of their own. As of 2006, former Parcells assistants who are currently head coaches in either the NFL or the college ranks include:
Bill Belichick, New England Patriots
Tom Coughlin, New York Giants
Sean Payton, New Orleans Saints
Romeo Crennel, Cleveland Browns
Eric Mangini, New York Jets
Al Groh, University of Virginia
Charlie Weis, University of Notre Dame
In addition, Parcells disciple Ray Handley served as head coach for the New York Giants from 1991 through 1992, and Al Groh and Chris Palmer served as head coaches of the New York Jets and Cleveland Browns, respectively, at one time.
Parcells, Belichick, Coughlin, Payton, and Mangini all were able to guide their respective teams into the 2006 playoffs, accounting for nearly half of the post-season field.
