"He got advice not just from his old man or his mom but from people like Peyton Manning, Eli and others who've gone through it," he said. "That information and that advice of course is invaluable."
Oliver also explained that he and Archie Manning, Peyton's father, were teammates on the Houston Oilers.
"Peyton kind of acted like a mentor to Andrew," Luck's father said.
Manning was said to have told Luck about his experience in 1997 when he returned to Tennessee for his senior year.
