Cubs Trade Cedeno and Olson for Heilman

The latest trade by the Chicago Cubs has many fans puzzled on what is yet to come. The trade sent the Mariners, Ronny Cedeno and Garrett Olson, and received Aaron Heilman. This puzzled me because I believed that since the new owners were in place that they would go after Jake Peavy once more and the Padres had Olson on their radar. I have not heard anymore rumors of whats to come but I believe Heilman will be an asset to the Cubs. He has started and pitched in relief in the Major Leagues so either way he can help the Cubbies out. I just hope that this does not kill the Peavy trade because the Cubs would benefit far more from him than Heilman.
