During the 9 game win streak, I referred to this team as an "island of misfits". Seems to be true. They are playing with house money. They know that there is little to no pressure on them to go anywhere this year, and you can see how much fun they are having as a result, like with the shopping cart stuff and waving back to the dugout after any XBH.
The Yankees meanwhile, look like they have stage fright, or at least that the lights of the spotlight are too bright. Those famous NY tabloids wrote them in as AL champs very early in the offseason, and now that they are struggling, every little mistake gets exaggerated, and you start overthinking the basics. You start trying too hard to win, and that's part of what's led to the HR or bust mindset at the plate.
