TEMPE, Ariz. (AP) -- If Bruce Arians is to become an NFL head coach anytime soon, it's going to be in Arizona.
The Indianapolis offensive coordinator, who went 9-3 as the Colts' interim coach when Chuck Pagano was being treated for leukemia, interviewed on Thursday with the Cardinals for the only job still open of the eight teams that fired their coaches after the season.
Afterward, the 60-year-old Arians said his stint as Pagano's replacement, in his words, "answered all questions I ever had" about whether he could succeed as an NFL coach.
"I hope it answered all the questions everybody else has had for all these years," he said.
Arians said there are young coaches for teams still in the playoffs that will be denied a chance to be a head coach now because of their teams' success.
"Maybe I was a victim of that a couple of times," he said. "Hey, I'll take the Super Bowl ring and look back later. You can't worry about why you never got one or why have you got one this time. I'm just happy it happened, and I look forward to seeing what's made of it and what turns out."
Arians has been a football coach since his days as a graduate assistant at Virginia Tech in 1975 and he has 20 years of experience as an NFL assistant. He also was head coach at Temple for five seasons.
Wearing a Super Bowl ring from his days in Pittsburgh prominently on his right hand, he said his stint as head coach in Indy taught him that being a head coach is "not as hard as it's supposed to be."
"It's really not," Arians said. "I think it's all about building relationships. Coaching is all about relationships. As long as it's built on trust, loyalty, and respect, anything is possible."
He is the sixth known candidate to interview to replace coach Ken Whisenhunt, who was fired after six seasons in Arizona. When the Jacksonville Jaguars hired Seattle defensive coordinator Gus Bradley on Thursday, Arizona's job was left as the only one still open.
Arians was wide receivers coach in Pittsburgh and he succeeded Whisenhunt as offensive coordinator there. He was Steelers offensive coordinator when Pittsburgh beat Whisenhunt's Cardinals in the 2009 Super Bowl. Arians left the Steelers to become Pagano's offensive coordinator last year, taking over as interim coach when Pagano left for treatment for leukemia.
"It has been an unbelievable 12 months for me personally," Arians said.
Among those interviewed by Cardinals President Michael Bidwill, Denver offensive coordinator Mike McCoy was hired as head coach in San Diego. Other known Arizona candidates are Cardinals defensive coordinator Ray Horton, Seattle offensive coordinator Darrell Bevell, Steelers offensive coordinator Todd Haley and Cincinnati offensive coordinator Jay Gruden.
Horton has a year left on his contract. Asked if he would keep Horton as defensive coordinator if he got the Arizona job, Arians declined to discuss the prospect.
"Right now it's way too early in the process," Arians said. "Obviously, I know Ray. I've got a history with Ray. But all those things would be way down the road. Guys are under contract. You can't really comment on staff members at this point in time."
Horton was defensive backs coach with the Steelers when Arians was offensive coordinator there.
The Cardinals had the worst offense in the NFL, and Arians downplayed any similarities to his offensive scheme and the one used by Whisenhunt. He said that after Whisenhunt left the Steelers for Arizona, he and Pittsburgh quarterback Ben Roethlisberger sat down and simplified the playbook.
Arians said his offense has some similarities but many differences from the one implemented by Whisenhunt.
Arians emphasized the importance of building a close relationship with the quarterback.
"As a head coach or an offensive coordinator, you're tied to that guy," Arians said. "Your future is him. You better realize that, and you better have a heck of a strong relationship so that when it's really tough in the game, he's telling you what he's seeing, not what he thinks you might want to hear."
Quarterback is a major problem for Arizona. The only one of the four who got a start in the Cardinals' 5-11 season that had any success was Kevin Kolb, and he went down with a rib injury in Week 6 and never returned. Arians said the Cardinals must either improve what they have at the position or find a new one behind what he called "Door No. 2."
He said he would call the plays as head coach "until I can find someone who is going to do it better than me. I haven't found him yet."
Arians was a finalist for the Chicago Bears job that went to Marc Trestman.
He said he would not leave Indianapolis for just any head coaching job.
"I said early when some teams contacted my agent about setting up interviews," he said, "I'm going to have a heck of a feeling about that organization, owner, general manager, team, to leave where I am right now."
Does he have that feeling with Arizona?
"Yes," he said. "I do."
