Jim Caldwell has been fired from the Indianapolis Colts. It appears that the Colts owner and new GM are building the new team around new quarterback Andrew Luck, the first player to presumably be selected in the draft. They will likely hire an offensive head coach to better develop Luck as a franchise quarterback. In all likelihood, Peyton Manning will either retire or be playing for a different team next year. With Luck on the roster, Peyton would have at most one year left of playing time with the Colts before they transition to Luck full time. Peyton probably would not like that situation for himself or his family, so he would prefer to get a long term contract extension for another team.
