NEW ORLEANS -- Looks like Jim Harbaugh needed less than 24 hours to get the hang of this Super Bowl media thing. The San Francisco 49ers' coach was a star Monday.Harbaugh, sometimes master of the awkward moment during his two-year run as 49ers coach, became master of Super Bowl ceremonies during an entertaining 20-minute session at the team hotel. He was at his best after Fox Sports' Nancy Gay asked Harbaugh a serious question about health dangers associated with football.
