I would again state that Frost holds a far more informed opinion of his coaches than the entire collective braintrust on these threads. However, the questions posed here are fair. Coaches are most likely to hire those they know will see the job of coaching as they do. As to why Verduzco worked long in "lesser" posts, allow the possibility that his strength is that of teacher vs orchestrator. He may not ever have had a desire to run things, rather, he the tool maker rather than user.
But more, i would welcome why you think Frost would retain Verdu's services if he found fault with them? Frost has demonstrated his willingness to move away from those not fitting the bill.
Coaching "success" is more than any one variable, and includes timing and fortune. That a coach is able to maintain a job at any institution, particularly in more recent decades, for 14 yrs as you note Verdu did at N Iowa, tells me all i need know.
No doubt, those working at the institutions you named will be surprised to hear themselves laboring in "oblivion".
