I looks like it will happen. The man who was the architect for the Red Sox two world series wins will now have the challenge of helping the Cubs win the big one themselves.
Jon Heyman of SI.com looks at the details of this transaction here: Epstein agrees to deal with Cubs
Here is an excerpt: "GM Theo Epstein has an agreement in place to become head the of Cubs baseball operations, SI.com has confirmed.
Sources indicate Epstein's move from the Red Sox should be completed within a couple of days. Sources say the two teams were still discussing Boston's compensation for allowing the move, but this is not expected to curtail a deal. It will either be cash or minor-league players going to Boston, but according to people familiar with the deal, the the Red Sox will be content with cash."
