I understand where you might think that, but it's a rather half-baked ideal. The Braves are footing a significant portion of the initial costs of the stadium, responsible for all overruns (which there will invariably be), and are also, with some support from private investors, behind the $400MM+ 'entertainment village' to be constructed around the stadium. Free public money is almost universally a good thing -- but this is no sweetheart deal like the Marlins conned out of the city of Miami (80% public funds, over half the money the Marlins contributed was borrowed interest free from Miami Dade).
We would all like to see a bump in payroll, and there just might be one between now and the stadium's opening as that seems to be a 'thing', but I personally think the Braves will be doing just fine if they are able to keep the payroll at its current level throughout the building of the stadium and beyond.
