Just to add to the intrigue, Lou Piniella has already come out and stated that he expects the Cubs to aggressively pursue a trade for Alex Rodriguez this off-season.
Piniella, the new Cubs manager, has a very close relationship with Rodriguez and also feels that it would improve the Cubs chances of winning.

My opinion on this is that I can't see it happening unless Carlos Zambrano is in the deal and the Cubs shouldn't even consider that. Now...if they could somehow swing a deal for ANYTHING other than Zambrano then that would be fairly interesting. I'd be especially excited if they could somehow get him and keep ARam as well but that's just the idle dreaming of a Cubs fan. I'd love to see an infield of ARam, ARod, Cedeno? and Derrek Lee. But I don't think I can see giving up Zambrano to get that infield. Maybe if they'd deal us ARod and Cano for Zambrano and Cedeno...but this isn't fantasy baseball.
