Indianapolis Colts offensive coordinator Bruce Arians is a hot head coach candidate, and his club will do what they can to keep him.

Arians not only groomed No. 1 pick Andrew Luck successfully, but he also served as interim head coach while coach Chuck Pagano was battling leukemia. Arians led the Colts to a 9-3 record and the Colts, after a 2-14 2011 season, is in the playoffs.

"We would try to do whatever we could to keep Bruce, but again, he's his own man and will make his own decisions," Grigson said on NFL Network's "NFL AM" on Friday. "It's kind of a great situation we have here. It's pure speculation, but we'd love to have him back."

Arians didn't thrive as a head coach at Temple. But he is a strong coach of the year candidate, given all the challenges the Colts overcame to have one of the best turnarounds in recent NFL history.

Asked by the Indianapolis Star if some team asked him about Arians, Luck playfully said, "Terrible.

"Just terrible.''

But Arians recently made clear that he wouldn't just leave to be a head coach.

"We'll listen to see if it's right for me and my family. I'm not just gonna run away to be a head coach, I'm not gonna do that," Arians told WHIP Radio. "I want to make sure they have a chance to win and see what the situation is, what city it is in.

"But definitely would listen, yes."
