Are the Braves really going to be improved at all compared to last year?

This off-season, they lost Bourn (6.4 WAR), Prado (5.9 WAR) and Chipper Jones (3.0 WAR).

They're replacing those three with B.J. Upton (3.3WAR), Justin Upton (2.5 WAR), Juan Francisco (0.8 WAR) and Chris Johnson (0.8 WAR).

That's a loss of 15.3 WAR, and a gain of 7.4 WAR.

I realize just comparing Wins Above Replacement is relatively simplistic, and I suppose you would expect both Uptons to be better this year than last because of regression, natural improvement and/or recovery from injury, but that still seems like a pretty sizable gap to make up. If anything, it seems like the Braves are treading water this off-season.
