Referee Lineage

[Mr. BenchPress]

This may be a bit off the wall, but maybe someone can piece this information together.

As many people are aware, the Bill Walsh "coaching tree" is famous for spawning, among others:

· Brian Billick
· Pete Carroll
· Bruce Coslet
· Tony Dungy
· Dennis Green
· John Gruden
· Mike Holmgren
· Steve Marriucci
· Ray Rhodes
· Mike Shanahan
· George Seifert
· Dick Vermeil
· Mike White
· Andy Reid
· Sam Wyche

On the heels of a few people on this board making note of Ed Hochuli's leadership abilites and the fact that he had the highest rated crew this year despite the relative inexperience of most of his guys, I was just wondering if a referee lineage similar to a coaching lineage can be drawn through the referee ranks? In otherwords, what referee has bred the most future referees?
