Here is my reason the Yankees care more about winning than the Cubs:
This happened...
I am sure we all remember Jeffrey Mayer becoming a hero way back when. After this, the Yankees tore down their beloved, history rich stadium and built a new one. Since then, there have been no interferences as big as Mayer's that I can think of in Yankee games. They saw a possible problem and made a change for the sake of winning. Plus, Yankee fans in fact are willing to give 100% on every ball to help their team whenever possible.
By now I hope you are thinking "what an idiot" as you read this stuff. It is all in fun and not actually the way I feel or even realistic. I hope Wrigley stands forever and given the chance I would rather punch a Yankee fan in the stomach over a Cubs one. I just hadn't posted in a while and this was the baseball bouncing around the melon this morning. Thanks for reading if you lasted this long into the post. Go A's!
