How much is that exactly? I have no clue. You have no clue. Is it material to the Braves bottom line? I highly doubt it. And if Markakis has a hot April then all of a sudden there are a bunch of new jerseys to buy.
The Bravs won't "lose" any more potential revenues than they'd have earned if Jason was here this season than they would've spent paying his salary.
Just for the *ell of it, let's say they don't sell
10,000 Heyward jerseys (at $100 each) - that's $1,000,000 the organization "loses". To get to "break even" on his salary, you'd have to sell
292,000 less tickets (at an average of $25 each) than the Braves did in 2014.
They're NOT losing money because he's not here - attendance would have to drop by 3,604 fans per game to get to that number. The last time attendance dropped that much was between 2000 and 2001 (the year Rico Brogna and Ken Caminiti replaced Galarraga, John Rocker was traded to Cleveland in June and the pen floundered terribly until Smoltz returned from TJS and saved the first 10 games of his career, B. J. Surhoff played LF, John Burkett was the #3 SP, Millwood logged 121 IP with a 4.31 ERA out of the #4 spot in the rotation, and Odalis Perez and Jason Marquis split the #5 SPs starts).
Before someone starts the argument that the attendance would be significantly higher IF we'd have kept Heyward and Upton, remember this...the attendance dropped from 39,930/game in 2000 to 34,858/game in 2001 (-5,072/game) while Chipper (.330/.427/.605/1.032, 38/102, 113 runs) and Andruw (.251/.312/.461/.772, 34/104, 104 runs) were in the prime of their careers and putting up SUBSTANTIALLY better numbers than Heyward and Justin have ever combined to approach.
Attendance dropped 2,400/game between 2013 and 2014 WITH Heyward and Justin in the lineup AND the team was coming off a 96 win season and Division Championship - the city of Atlanta hasn't supported the Braves (regardless of who the players are) IN YEARS.
