Andrew Luck believes he is ready to start in the NFL next season. Colts owner Jim Irsay has said he will use the No. 1 overall pick on a quarterback, especially with Peyton Manning's health still unresolved, and Luck is expected to be that man. Luck says he could co-exist with Manning, but he wants to play right away. "From what I understand, he means so much to this city. Not just for the football stuff, but what he's done off the field," Luck said. "Obviously he's a great guy from a great family. You don't ever replace guys like that."
