Liberty Media owns a ton more than that as well. The bottom line is at last check Liberty Media has around $40 BILLION in total assets. Heck, their sports interests go beyond the Atlanta Braves: they even own the whole Formula 1 Racing series and was recently asked if they would be interested in NASCAR if it was on the market. The answer was yes.
So as you can see, and probably already knew, this company is not hurting for money. So why therefore are the Braves not spending with the likes of the Yankees, Red Sox, Cubs, Dodgers, or Nationals for that matter?
