Pep Hamilton, the Stanford offensive coordinator, whose official title there in 2011 was "Andrew Luck Director of Offense," is now Luck's director of offense once again, according to ESPN.com.

Hamilton will replace Bruce Arians as the Indianapolis Colts offensive coordinator. Arians was hired by the Arizona Cardinals to be their new head coach.

Hamilton's familiarity with Luck should help switching to a new offensive coordinator a seamless transition for the 2012 overall No. 1 pick, who guided Indy to a playoff berth in his rookie season.
