INDIANAPOLIS (AP) -- The Indianapolis Colts have their new offensive coordinator, and it's someone Andrew Luck already knows.
A person familiar with the decision said Stanford offensive coordinator Pep Hamilton has accepted the same position with the Indianapolis Colts, where he will be reunited with Luck.
The person spoke to The Associated Press on the condition of anonymity Friday because the deal has not yet officially been announced by the Colts. Team owner Jim Irsay tweeted that the Colts' offense "could have some pep to it this fall."
The Colts were hoping that a promised pay raise and a new job title would be enough to keep Bruce Arians in Indy.
But Arians, a longtime NFL assistant, had long dreamed about being an NFL head coach and couldn't say no when the Arizona Cardinals offered him the job Thursday.
Arians stepped in when Chuck Pagano was diagnosed with leukemia in September and went on to tie an NFL record for wins after a midseason coaching change. His 9-3 record not only made him a front-runner for coach of the year honors, but suddenly made him a hot commodity on the interview circuit, too.
Knowing that, Colts general manager Ryan Grigson said Tuesday that while he was hoping Arians would return for a second season as offensive coordinator, he was preparing for life without the 60-year-old Arians.
"I take it upon myself to always be prepared. Just like during the season, I always have a doomsday mindset," Grigson said Tuesday. "I always have a deep reserve of players and people at the ready. That's my job. That's what I've been entrusted to do. I'm just doing my job. It's not cold or heartless, I'm just doing my job."
Grigson played it coy earlier this week when he was asked whether Plan B would be promoting quarterbacks coach Clyde Christensen to offensive coordinator, a job he held under former coach Jim Caldwell.
But one thing the Colts wanted was continuity for Luck and his young teammates and Hamilton could help in that facet.
He'll have some familiar faces on the roster with Luck, last year's No. 1 overall pick out of Stanford, and tight end Coby Fleener.
Luck set NFL rookie records for attempts and yards passing and fell just short of the league's rookie marks for completions and touchdown passes. He tied the league's single-season record for most winning drives in the fourth quarter (seven) and produced a league-high nine wins in one-possession games.
Hamilton also has a solid supporting cast outside of the two ex-Cardinal players. Running back Vick Ballard, tight end Dwayne Allen and receivers T.Y. Hilton and LaVon Brazill combined with Fleener and others to give Indy (11-5) the highest combined total of yards rushing and receiving by rookies on one team since the 1970 AFL-NFL merger.
Hamilton joined Jim Harbaugh's staff at Stanford in 2010. He was promoted to offensive coordinator when Harbaugh left for the San Francisco 49ers two years ago and David Shaw took over as Stanford's head coach.
Last May, the university officially renamed the offensive coordinator position the "Andrew Luck Director of Offense" after an anonymous donor made what the school called a "very generous" gift to honor the record-setting quarterback.
Stanford has endowments for many positions in the athletic department, although most are reserved for head coaches and the athletic director.
Hamilton helped continue Stanford's renaissance behind a balanced offense -- with and without Luck.
One of the Cardinal's key recruiters, Hamilton also discovered new quarterback Kevin Hogan out of McLean, Va. The strong-armed and quick-footed Hogan finished 5-0 -- including beating four ranked teams en route to the Rose Bowl win over Wisconsin on Jan. 1 -- since replacing Josh Nunes, who struggled to succeed Luck. Stanford had not won the Rose Bowl since 1972.
Stanford is one of only three schools -- Oregon and Wisconsin being the others -- who earned BCS bowl berths the past three seasons. The Cardinal routed Virginia Tech in the Orange Bowl two years ago and lost in overtime to Oklahoma State in the Fiesta Bowl in Luck's finale.
Stanford has won at least 11 games each of the past three years. The program had won 10 games only three times before (1992, 1940 and 1926).
Losing Arians is only part of Indy's transition.
Since losing a wild-card round game to Baltimore, the Colts have parted ways with special teams coordinator Marrwan Maalouf and watched vice president of football operations Tom Telesco leave to take the general manager job in San Diego.
