NEW ORLEANS -- The San Francisco 49ers celebrated a significant victory Thursday. They completed a media schedule far more demanding than players new to the Super Bowl experience could have anticipated."Thank God," veteran tight end Delanie Walker said with a laugh.Walker awakened in the 49ers' team hotel at 8 a.m. CT and was seated at an interview table in a downstairs ballroom 20 minutes later. This was his third consecutive morning featuring an hour-long session for the 49ers.
