Question: Who is the son of the son of former Saints coach Bum Phillips that coached for both teams in the Falcon, Saints rivalry?

The Buccaneers–Saints rivalry is between the Tampa Bay Buccaneers and New Orleans Saints.  The two teams met for the first time in 1977.  The expansion Buccaneers had been winless over their first two seasons to that point, and entered the game with a collective record of 0–26.  Tampa Bay upset the Saints, earning their first win in franchise history. <SEP> Morten Andersen (born August 19, 1960), nicknamed "The Great Dane", is a Danish former American football kicker and All-American at Michigan State University.  He is the all-time leader in games played in the NFL at 382; in addition, he also holds the distinction of being the all-time leading scorer in NFL history, and when he retired he was the all-time leading scorer for two different rival teams; the New Orleans Saints, with whom he spent 13 seasons, and the Atlanta Falcons, with whom he spent a combined eight seasons. <SEP> The Falcons–Saints rivalry is a divisional rivalry in the NFC South of the National Football League (NFL) between the Atlanta Falcons and New Orleans Saints.  The series is by far the oldest and most established rivalry in the division.  They have also drawn coaches from the same families, and even shared a head coach: recent Falcons coach Jim L. Mora is the son of longtime Saints coach Jim E. Mora, and former Falcons and Saints coach Wade Phillips is the son of former Saints coach Bum Phillips.  Founded one year apart, the Saints and Falcons were the first two NFL franchises in the Deep South (Washington, Dallas, and Miami being arguably southern but not in the "traditional" Deep South).  They have shared some important players, such as kicker Morten Andersen (the leading scorer in New Orleans history), Bobby Hebert (who quarterbacked for both teams in the 1990s), and Joe Horn (the Pro Bowl Saints receiver who left for the Falcons in 2007). <SEP> The Exeter–Andover rivalry is an academic and athletic rivalry between Phillips Academy (Andover) and Phillips Exeter Academy (Exeter), bearing many similarities of tradition and practice (as well as athletes) to the Harvard–Yale rivalry as Exeter traditionally educated its students for Harvard, much as Andover traditionally educated its students for Yale (despite being in the same state as Harvard).  Today, Phillipians and Exonians continue to matriculate in large numbers to both Harvard and Yale, as well as many other top universities.  The athletic rivalry between these two schools began with baseball, and football soon followed the same year.  Today the two schools face each other in several sports every fall, winter, and spring trimester.  The rivalry is America's earliest between preparatory schools.  The two schools were also two of the three schools (the other, Lawrenceville), who became the three first schools in the United States to form secondary school lacrosse teams in 1882.  Similar boarding school traditions include the Choate–Deerfield rivalry, Hotchkiss–Taft rivalry, the Blair–Peddie rivalry, the Hill–Lawrenceville rivalry, the Groton–St. Mark's rivalry and the Loomis-Chafee–Kent rivalry.
