I live about half way between Atlanta and Charlotte (about 120 miles from each), and both of the NBA teams are now blacked out on all the multisports package channels. I used to get both teams on FoxSportsSouth, and the then Charlotte Hornets on Turner South. Now nothing. I do get the Braves and the Thrashers, but I could get them on SportsSouth and Turner South without subscribing to multisports. So as far as MLB and NBA is concerned, multisports package has not really added anything. Maybe the tail end of a baseball game if it goes over three hours. It probably is not worth the cost for most people.
PS. I do occassionally get a game on the NBA channel, but rarely a team I am interested in so I had forgot about this.
