There's no way the Yankees give up A-Rod's offense for just pitching, especially damaged goods like Prior. He couldn't just come back healthy next year for this to work...he'd need to at least be back at his 2003 level. The Yankees need pitching and they need it badly. They already have the best offense in baseball, and with the addition of Abreu they can afford to sacrifice some offense. The Yankees are a smart, well-run organization. I think they would need to see if Prior was healthy b/f they would consider the deal. As they're showing right now, they don't need it THAT badly. Again, I'm not saying it's impossible, I just very much doubt they do Prior for A-Rod straight up unless Prior magically regains his 2003 form. The Cubs would have to probably add on a couple players at the very least.
