Calm down, guys.
Here's my theory: A-Rod had such a good year because he hit rockbottom in his life and had nowhere else to go but up. He did go up and, because he went up, his self-confidence went up, which is why he felt comfortable enough to break up with Ms Hudson.
Of course, I have no idea if that's what happened. But, being an A-Rod fan, I hope that it is.
