LONDON -- From staying the week on the English countryside to experiencing Winston Churchill's War Rooms to getting chills while listening to "God Save the Queen" before the game to watching his team put on a clinic in front of 83,000 fans at Wembley Stadium on Sunday, it was quite the week for Jim Harbaugh."What a great experience," the animated 49ers coach said Sunday after seeing his team dismantle the winless Jacksonville Jaguars 42-10 to complete the first half of the season.
