You have a statement from Liberty subject to SEC regulation that states that after all of the increase in payroll and all of the increased expenses, many of which would be one time expenses, the Braves were significantly more profitable in 2017 than in 2016. Not revenues. Profits.
You are arguing that the Braves have a lower payroll therefore the Braves must be facing financial distress that isn't shown on the books. And to get there you have to make the assumption they aren't paying money that that a lot of people are assuming that they are paying.
Other than the Braves actually seeming to have a reduced payroll from what they had after acquiring Matt Adams, I'm not sure there is really any indication that they are struggling financially.
Liberty might well have set a payroll lower than the Braves revenues would support. Or maybe there is some expected expense or vast decrease in profits that they are anticipating. All of that is without any direct evidence at this point. Would love the beat writers to pursue it.
