If you read the Braves fan sites, they've been ripping Bourn (because he strikes out so much and tries to be a power hitter), Uggla (because he can't hit or play defense) and McCann(he's injured and can't hit).
I haven't read Braves fan sites, but I hold my breath every time Bourn, McCann, Prado, or Heyward hit. Uggla? Not so much, although his fielding makes for interesting plays.
