I'm not sure I see your point. Before our recent home winning streak, the last season we went undefeated at home was 2002-3. We lost four games at home in 2006-7. Even the 2001 champs lost a couple games at home (albeit to Carolina and fellow Final Four team Maryland).
Cameron still is sacred, but that never meant that we don't lose there. That's really just an angle that ESPN likes to play up when we're on a winning streak. (Especially when that winning streak ends or, better yet, barely survives.)
