The Colts selected the former Stanford quarterback with the No. 1 overall pick on Thursday night, making him the heir to the throne Peyton Manning vacated when the Colts released him earlier this offseason.
"You don't really replace a guy like that," Luck said. "You can't. You just try to do the best you can. Obviously, he was my hero growing up."
The Stanford quarterback was told by the Colts last week that commissioner Roger Goodell would announce his name first on Thursday night. He got the nod over Baylor QB Robert Griffin III, the Heisman Trophy winner who was taken second overall by the Washington Redskins. Washington acquired the No. 2 overall pick weeks ago in a trade with the St. Louis Rams.
