Where are you going to find one? Those guys rarely change jobs. You act like there are top head coaches ready and waiting to leave their established program high paying jobs for a rebuild that will pay the same or possibly less.
And the thing is every coach starts out as a guy with little to no head coach experience. Take a look at the current top 25....
2019 College Football Rankings for Week 5 | ESPN
Dabo Swinney- Coordinator with no HC experience that was promoted to head coach.
Saban- self explanatory.
Kirby Smart- Saban coordinator with no head coaching experience prior to UGA.
Ed Orgeron- Ole Miss was his first HC job. He's doing well at LSU so far.
Ryan Day at Ohio St- No head coaching experience and was promoted after Urban retired.
Lincoln Riley at Oklahoma- No HC experience and promoted.
Gus Malzahn- He was Arkansas St's HC before Auburn. They took a chance on a non power 5 guy and it's worked well.
Paul Chryst- Was Pitt head coach before Wisconsin. HC experience but not major school exp.
Dan Mullen- Miss St HC experience before Florida.
Bryan Kelly- Central Mich and Cinn HC before Notre Dame. Not sure he would have been called A-List before Notre dame
Tom Herman- Houston HC before Texas.
James Franklin- Vandy HC before Penn St.
Mario Cristobal- No HC exp prior to Oregon.
Kirk Ferentz- Maine HC from 90-92. Otherwise position coach/coordinator
Justin Wilcox- No HC prior to Cal.
Bryan Harsin- Ark St head coach prior to Boise St.
Chris Peterson- Boise St head coach prior to Washington
Bronco Mendenhall- BYU head coach prior to Virginia
Kyle Wittingham- No HC experience prior to Utah
Jim Harbaugh- Wide variety of NFL and college HC experience prior to Michigan
Clay Helton- No head coach exp prior to USC. Did interim a small amount.
Josh Heupel- No HC experience prior to UCF.
Jimbo Fisher- FSU head coach prior to A&M
Chris Klieman- North Dakota St HC prior to Kansas St
Mark Dantonio- Cincinnati HC prior to Mich St
Pretty much all of these guys were not proven A-List Power 5 head coaches when they got their current job. How many would I say were A-List proven Power 5 head coaches as you think is required when they got their current job?
Saban- proven college coach and Bama lucked out he was unhappy in the NFL
Peterson- Yea it's Boise St, but he took them to top 5 rankings and BCS bowl game wins.
Harbaugh- A lot of HC experience in college and NFL. Moved from the NFL and came home to Michigan
Fisher- NC winner at FSU and became unhappy there.
There were some guys that had success at smaller programs as head coaches but their experience is very similar to what we saw in Butch. Malzahn, Kelly, Herman, Mullen, Chryst for example. Many of those guys were only coordinators.
You want a proven A-List power 5 head coach? You have to luck out and be the guy that finds him for the most part.
