Only if you are a child.
Grownups understand it fine lil guy!

Says the mature guy who can't get over the fact that the Red Sox will at least tie the Yankees for rings this decade.
I haven't been around before the invention of color television, so maybe I have a slightly different outlook then you. I was born in an era where almost everyone my age was a Yankees fan because that is when they finally began to win again (late 90's). I was a Boston fan and a proud one. Did 2003 hurt? You bet your ass.
Yet, that makes me just more of a fan. It take balls to stand by a team like the Red Sox or in Elvis's case the Cubs. It doesn't take any balls to stand by a team like the Yankees where it's basically like going to the Casino and rooting for the House to win.
So do not tell me what I do and do not know. I've felt disappointment as a Red Sox, I've felt triumph. But you know what? That's being a Red Sox fan. You win some, you lose some, and sometimes it all just goes to hell. I've told plenty of my friends that being a Boston sports fan should come with a health plan.
So go ahead, celebrate what the Yankees won long before I or most of the people on this board were born. Seriously, it's no skin off my back. However, don't expect me to take you seriously when you want to have a current discussion of this decade.
If the Yankees win this decade, would it be tough to not choose them for best team? Yes. However, if all you do is look at statistics like you and Andrew seem to be doing, then you miss a huge part of the game.
