Bill Parcells is not only one of the greatest coaches in NFL history, he's also one of the most influential as well.
Parcells' track record speaks for itself: two Super Bowl victories with the New York Giants, a Super Bowl appearance with the New England Patriots, and an AFC Championship Game berth with the New York Jets.
The Tuna was named AP Coach of the Year twice, and is the only coach in NFL history to lead four different teams to the playoffs.
His influence has also spread beyond the playing field and into the coaching ranks as well.
Seven former assistants are currently head coaches in college or the NFL, and five others previously served as head coaches at the NCAA or pro level.
It's quite an impressive coaching tree to say the least.
The following is a ranking of all the Tuna's assistants who have gone on to become head coaches in college or the pros.
