The Notre Dame coaching formula is very, very simple
Since Leahy, there has been one sustainable quality that determines success as head coach
at Notre Dame: Extensive major college head coach experience.
Ara Parseghian had been successful for years at Northwestern, and had been coaching college
ball for several years before that.
Dan Devine had been ultra-successful at Missouri, and in addition to coaching the Packers,
he had several years of general college coaching.
Lou Holtz had successful stints at William & Mary, NC State, Arkansas and Minnesota,
as well as several years as an assistant before heading to South Bend.
These three coaches each won National titles at Notre Dame.
Those that did not do quite so well: Joe Kuharich, Gerry Faust, Ty Willingham, Bob Davie,
and Charlie Weis simply did not have the extensive major college head coaching experience
that the job requires in South Bend. The NFL does not prepare you, high school ball does
not prepare you, assistant coaching does not prepare you, and minimal years as a head
coach will not do the trick either.
If ND goes with somebody out of the NFL, or somebody that has been a long-time assistant
someplace, they'll be going through the same thing in 3-5 years, mark my words.
However, if they choose a successful major college head coach with many years of
head coaching experience, Notre Dame will once again become a force in major college
football- almost guaranteed.
That's why Brian Kelly makes sense for them.
