 Jack was flying home from Australia, where the Red Sox win might not have made the news and he might not have been interested in the sports pages anyway, given the reason he was there.  Since it's a saying of his dad's, there's also no reason to believe that Jack would follow the Red Sox or have any interest in sports.  How long was his dad gone?  He could have left the night before this big Red Sox game. So...around Halloween 2004 maybe, but not definitely before.
