There’s a line from Game of Thrones from a character talking about Tywin Lannister, the late head of House Lannister and Hand of the King to his grandson Joffrey at the time. To paraphrase, this character (I don’t remember who or when) says Tywin is ruling the Seven Kingdoms “by sheer will.”
Like the Lions of Casterly Rock, the Yankees are rich – but are working through money problems. They have a track record of winning – just not so much lately. They also share a certain sense of superiority, which results in them being disliked by most.
