I have a friend who once took his 12 year old son to a Yankees game after the son had been requesting same for a long time. As they were leaving, the son remarked “Hey Dad, those people are all assholes!”
He immediately changed to the Mets - all your championships didn’t count with him or with lots of people.
Steinbrenner is the one who started the death of baseball by refusing to abide by an accepted, but unwritten, salary structure.
That horse left the barn by the time George - who saved the NY Yankee franchise - ever got to the Bronx. He grasped what could be done before others did and won a couple of championships in the 1970s. Big fatdeal. Then he screwed up the Yankees so bad that from 1981 - 1996 they didn't make a single World Series.
"Unwritten salary structure" - yeah - how well did that work out for baseball when Peter Ueberroth got the owners to implement it in the 1980s? Not too well.
I will give you one thing - your son was probably right about the rowdies in the stands. Been there, seen 'em myself. (Of course, the tickets are so expensive now that I'm not sure that bunch can afford to get in anymore). First NY game I went to was against Boston in 1977 - when the Yankees got way behind, fights started breaking out in the stands. I think they have that stuff under control these days, though. That was a different era.
