Turner Field Capacity - 50,096
The seasons you reference and their average attendance...
2015 - 24,709 (49.323% of capacity)
2014 - 29,065 (58.019% of capacity)
2013 - 31,465 (62.809% of capacity)
The Ted was almost 40% EMPTY during regular season games even when the team made the playoffs WITH Heyward, Upton, and Gattis on the roster. It was 42% EMPTY the last season the Braves had those players.
Fans haven't SUPPORTED the team - actually come out to see the games - since 1999. The average attendance for home games that year was 40,554 (80.952% of capacity - or 9,089 more tickets sold per game than when they made the playoffs in 2013). You do the math - 9,089 x 81 x $25 = $18,405,225 more to spend on salaries - and that's if $25 is ALL those extra fans in attendance spent while at the park - it doesn't include parking revenues and apparel sales. Not coincidentally, the Braves had the 2nd highest payroll in 1999 coming off a 1998 season where they averaged 41,492 per home game.
They can't make it much simpler - if fans actually came to the games, they'd spend more money on payroll.
But it's an if/then proposition.
If you put a better product on the field, one that produces some excitement and with some marketing behind it to draw in the
average fan, then fans will come. You invest in the product and it will pay off if those investments are wise investments. If you look at the Braves payroll and adjust for inflation of the cost to run the franchise, the payroll is significantly lower each year even as it stays relatively stagnant.
The other part of it is that the Braves, even with all the success of the 90's and 2000's, still only one
one WS. I think a lot of casual fans that could have been developed into more loyal fans never were because of the perceived lack of success. I think a lot of casual fans soured on
the Braves way because they associated that with good, but not good enough.
And then the final thing is the park and its location. A lot of fans just have no interest in in taking their family into Atlanta proper for a game, call it racism, call it fear of crime or just general fear, call it avoidance of hassle, call it what you will but its there.
Running the team like they have been running it is just one thin mistake (probably already made back in 2013 or so) from locking onto the downhill rails with no way off until the train hits bottom (poor team, attendance declines, payroll lowered, poor team again, attendance continues to decline, payroll lowered again with justification essentially sayings fans won't come and spend big money to watch our ****y product so we can't afford to invest to make it better, all on a downward spiral right to the late 70's.
