Someone had mentioned Braves attendance awhile back.
through 41 games:
2017 1,247,027 (30,415)
2018 1,305,399 (31,839)
2019 1,275,191 (31,102)
Running a bit behind last season overall, but it's hard to say whether there has been a similar mix of weekday/weekend matchups and quality.
Probably something right about 2.5m is about right as last season's projection slightly lagged behind 41 game estimate.
