The Girl with the Dragon Tattoo star Rooney Mara could have had a high flying career as a sports executive….but she wasn’t interested.
  Rooney, 26, who has been nominated for a Golden Globe for her role as the tattooed and psychologically troubled Lisbeth Salander, comes from a powerful and wealthy sporting dynasty: her two great-grandfathers founded the Pittsburgh Steelers and New York Giants NFL franchises and her father and uncle are both executives with the Giants. 
  “I was never much of a sports person so it was pretty clear from the beginning it wasn’t going to be my path,” she told me.  
  Instead she followed her sister Kate Mara into acting, but, she says: “I never really took myself too seriously.”
  Now, with film offers pouring in and a likely Oscar nomination looming, she’ll have to.
