The point of the post is that there is a direct correlation between bumping the payroll to make the team better and having better attendance....
If say the Braves went out this offseason and got Donaldson, JTR, plus say a Keuchel or Kimbrel, you would imagine that the fan base would turn out in better numbers throughout the season as opposed to bringing in Donaldson, McCann, and Markakis. A better overall product on the field should lead to increased fan attendance.....meaning more money spent on parking, the Battery, drinks/food/souvenirs sold in Suntrust Park...on top of increased ticket prices.
When people are being told by everyone in the media that the Braves are likely a 4th place team in the division, most people won't spend the money to go see them. That's why last season, the fan attendance really spiked towards the end of the season. And the 1 home game we played in the NLDS had an atmosphere that was unbelievable.
