The Colts have extended the contracts of team president Bill Polian and son Chris through the 2012 season. Chris, who served as vice president of football operations for four seasons, is now the team's general manager. He will assume the day-to-day operation of the franchise whenever his father steps down. "There is no seismic shift. Nothing will change anytime soon," owner Jim Irsay said. "But continuity is important to me."
