This is from today's NY Times article by Murray Chass who queried most of the GM's about A-Rod. While I realize that it is part of his job not to reveal too much, I personally take this as a pretty definitive quashing of the Cubs getting A-Rod idea which is fine with me.
"Jim Hendry of the Cubs said: "He's a great, great player. I know he has a longstanding relationship with Lou Piniella. Anybody would love to have him. In our situation we're very happy with Aramis Ramírez at third. In the overall scheme of things, for the dollars it would take, we have other needs -- in the outfield, speed-wise, maybe a little more pitching.
"For that kind of volume of dollars, I don't see a way that would make any sense because we're very happy with our guy at third. To commit that much more to one player and not address the other needs we have when we already have an All-Star caliber third baseman is really tough to do."
For complete article which seems to indicate Boras may have overplayed his hand
Apologies if similar comments are in the Chicago papers as well but I can't read everything
