With the first major move of the off-season, the Atlanta Braves acquire second baseman Dan Uggla for left-hand pitcher Mike Dunn and utility man Omar Infante.

I just want to say, welcome sir.
This is crucial. Trading for a high caliber second basemen shows just how questionable Chipper Jones is. Braves fans do not want him to go, but it looks like the team is prepared for the worst. With Uggla starting at second base, Martin Prado can move permanently to third if needed. If Jones does come back, Prado has the ability to play the outfield. Another option could see Prado at first base if Freddie Freeman doesn't work out as planned.
I'm also not sure why the Florida Marlins would have traded such a valuable player within the division. They received two high caliber players and left a small hole in the bullpen and on the bench of the Braves, but I feel Uggla will have the better return. An exciting move for the Braves, but personally, I hate to see Dunn and Infante go.
