(I recognize the joke and choose to ignore it)

Everything.

A tiny list:

Continuing to count World Series wins from the early 1900s when there were like four teams competing at a serious level. It's a joke.

The fans. No elaboration

Many of the big name players "a rod" most of all are just assholes. No one will deny their skills, but just be humble. A little humble.

Along with having big name players, baseball is kind of weird in that teams literally can just straight up buy talent. It's a genuine issue in the sport and the Yankees are the prime example. They make fuckloads of cash from their team, annoyingly, being the team non-sports fans associate with baseball as a whole and buy the caps and whatever. Then they spin that money into signing the best players they can from other teams. It just consolidates and perpetuates the problem. No team can compete with the Yankees being able to offer $250M contracts. And no that isn't to say the players don't "deserve" the high salaries. They deserve almost all of it. The problem is it's hyper concentrated into specific franchises and yeah. I don't know any solutions that wouldn't immediately get shot down by team owners, which is precisely the problem at the core. There shouldn't be owners or cash pools for specific franchises. But good luck getting any of this into basically anyone's brain that a major problem in the sport is capitalism. They're likely to spin it as being salty, being jealous, say it'll hurt players, etc. without seriously engaging in the problem that the Yankees are basically a symptom of (so in a way, I'm hating the players and not the game- but also fuck the Yankees. 🤷)

Oh also their apparently 10000 year old owner continues to require players shave and maintain some weird 1950s leave it to beaver looking aesthetic. Every other team has long ago joined modernity. That weird control freak shit is another symptom of allowing individual owners to exist
