Yes the Braves do have the best defensive outfield in baseball and it isn't even close.

By WAR they are behind the Cards but they are throwing two utility players in Craig and Schumaker in there with the regular outfielder of Holliday, Jay, Beltran. The Angels are right behind the Braves but more than half of their overall outfield WAR is Trout. So overall I give the edge to the Braves by a wide margin when it comes to the best outfield in the game.
Their infield defense is pretty poor at second and third. Chipper is good at positioning, but if he has to make any type of play on a ball he struggles, and Uggla is just bad. There are times in baseball when you just have to go with what you know and until defensive stats are better defense is one of those things.
