"We didn't argue about his defensive philosophy,” Castiglione said with a laugh. "I wanted to learn a certain amount about his coaching philosophy. How he would think through his role as a head coach. How he would develop his program.”
Castiglione sought out all sorts of details, including game week preparation, recruiting philosophy, the importance of academics, the hiring of staff, what kind of offensive scheme Stoops might favor.
Then Stoops surprised Castiglione.
"One thing I never heard, ‘Give me five or six years.' Never once did he say that or infer it,” Castiglione said. "He said, ‘I don't think I would be fair to the players that we inherit or that we recruit that first year, if I didn't give them the best chance to be successful.
"‘I have to ask them to buy into my system. And I have to put them in the best position to be successful. I don't want to just throw away a year by excluding them from the process of building this program.'
"When he told me that, that was one of a number of things that just clicked with my philosophy.”
Castiglione said he was acutely aware of the plight of OU players. The Sooners were about to have their fourth coach in five years. For the seniors, their time under Gary Gibbs, Howard Schnellenberger and John Blake were filled with disappointment and turmoil.
"We wanted them to have the best overall experience they could for as long as they were going to have eligibility,” Castiglione said. "Give them the chance to have a great experience, so they would remember that year as being something very important, that they contributed to this future success of the program.”
Stoops let it be known, the future was now.
"When he said that,” Castiglione said, "I'm thinking to myself, ‘All right.'
"Sometimes, at the end of the day, even though you have all the pieces together, there's something that grabs you in the gut and you know, that's the right one.
"With Bob, after that meeting, he got in my gut.”
The Iowa bombshell
Castiglione moved forward, conducting some interviews over the phone, one more in person with a standing head coach.
As was the case then, the Sooner athletic director still declines to name names out of ongoing respect for those involved and in keeping his word. Besides, who else had a chance?
Castiglione took the next step with Stoops, arranging another Admiral's Club interview that Sunday, this time with Boren, three regents, a booster, Neinas and Crowder.
Neinas — frequently used in coaching searches — informed the group that he had then-TCU coach Dennis Franchione on standby to come for a chat, if needed.
The group meeting with Stoops went brilliantly.
And when Stoops stepped out for a moment, a buzz filled the room.
Neinas and Boren announced that no more interviews were necessary, that OU had found its man. Soon everyone was in agreement and Castiglione joined Stoops in an adjoining room to discuss details of a deal.
"Bob Stoops had what I always thought important in a young head coach, and that's pedigree,” Crowder said this week from Boulder. "As far as being a good player, growing up in an environment of coaching, moving into his own career in coaching, he had about as good a pedigree as you could hope for.
"It became clear, this is the guy. By the time we finished that meeting, it was absolutely unanimous that this was the guy.”
Soon, Stoops was tempering the enthusiasm.
Yes, the interview had gone well, but Stoops had a commitment to talk to the folks at Iowa.
The same Iowa where Stoops had played and met his wife Carol and began his coaching career under Hayden Fry, who was retiring.
"I felt out of respect — I had been there 10 years, that's my alma mater — that I owed that to them,” Stoops recalled. "I'm a loyal person that way. I felt that I owed them that.”
For Castiglione, it only raised Stoops to another level. Still, it was hardly an encouraging revelation.
"You start to wonder,” Castiglione said, "the heart strings are tugging at the alma mater, they start rolling out the black and gold carpet, who knows who they roll out at this meeting, maybe coach Fry himself.
When Castiglione walked back through the door into the conference room, Boren and the others knew something was amiss.
"They knew when I walked in, they could just tell from my body language,” Castiglione said. "They said, ‘What?'
"I said, ‘Well, the good news is there's a characteristic here, if you can look beyond what I'm about to tell you, that just endears him more to the University of Oklahoma. But there is an area of concern.”
Stoops left to catch a flight for Iowa. The OU contingent talked, feeling confident and holding the framework for a deal with Stoops.
"All we could do was be patient and wait,” Castiglione said. "And that was a grueling 24 hours.”
In the end, there was no need for concern, although it did exist.
At that meeting with Iowa officials, however, athletic director Bob Bowlsby didn't roll out any black and gold carpet or enlist Fry to welcome Stoops home.
Instead, Bowlsby told Stoops they were considering him, as well as others.
"Fortunately,” Stoops said, "I realized that soon into the interview and made sure that everything was OK at Oklahoma.”
Oh, everything was OK, as soon as Stoops called with the good news that he'd be returning — for good.
Castiglione had gone to Boren's office that afternoon, where he nervously awaited Stoops' delayed call.
"I had my phone with me and finally got the call,” Castiglione said. "Bob had accepted the job.
"Of course, we were all ecstatic.”
The next day, Tuesday, Dec. 1, Stoops was introduced as OU's 21st head coach on the front porch of Evans Hall on the north oval.
Nine days after the firing of John Blake, Castiglione's search process came to a close.
Just like Blake's firing, there were initial mixed reviews, even among those in the media.
"I remember several people pointing their finger right into my shoulder saying, ‘I hope you realize what you have done,'” Castiglione said. "Basically, they were inferring we should have hired a sitting head coach.”
Such sentiments didn't last long.
"Now,” Castiglione says, "everybody says, ‘Oh, this was an easy hire. Bob Stoops was a no-brainer.' ”
