It's not that people don't care about baseball, it's that far more people care about football and ratings is all ESPN care about.
They do not (and if this thread isn't proof, I don't know what is) give a flying fuck about providing the consumer with the best total sports coverage. They do care about putting on whatever is going to get the most eyes glued on their screens.
So if talking about the preseason generates more money for them, they will fucking do it.
Much like how TSN (ESPN partly owned) will spend 75% of their SportsCentre broadcasts talking hockey. It's what gets the most viewers.
The concept of providing "total sports coverage" by the ESPN machine is a fuckin myth.
Stop paying for TV.
