Yeah the Yankees story is pretty good. They were written off early in the play-in game!
I too would root for the Dodgers over the Yankees. But also, while my rooting interest wouldn't be strong and the hype would be unbearable, it's hard not to like such an historic, high-wattage, big-market match-up on some level. Ratings may even go up this year (not that young viewers watch actual TVs). Unless the Dodgers keep buzzsawing.
Both teams are pretty likeable IMO, as far as what they are right now. Yeah, they have stupid money to pay for their mistakes but Cashman has always been good at his job and the Dodgers have a cutting-edge front office. Roberts would also become just the second African-American manager to win a World Series (we all remember the last guy).
