There is a huge difference between being just over .500 and having the best record in the NL, but I think you know that.
If your point is that every baseball observer would be shocked the Braves were over .500 at this point, I think you are wrong. I don't think anyone would be hugely surprised that a team predicted to be slightly under .500 ended up being slightly over .500 through June.
Particularly not a team with as much young talent as the Braves.
this is sort of a weird discussion because no one was talking about your being wrong, but you decided you needed to interject about how you were actually correct.
Let me try and break this down for you. The Braves increase in attendance is because they are winning. If they were playing like virtually everybody thought they would then it would decrease. If they were merely 5 games over .500 at this point then it's likely attendance would be flat. Any thought of what the attendance is going to be at the start of the season should be directly tied to how you think the Braves will play.
So I stand by my original comment. It's was a logical conclusion that attendance would drop if you are of the belief the Braves would end the season in the 70's in wins. If you thought the Braves would be over .500 at this point then yes you shouldn't think attendance would drop from last season.
