Fred Mitchell speculates that John McDonough might be headed to the Packers. He also mentions the Blackhawks as a possible destination. Sorry I don't know how to paste a link better than the one below:
Obviously with a future sale of the Cubs, McDonough isn't guaranteed a job. I don't think he's done a bad job in his time in charge. Maybe keeping Hendry wasn't the best decision, but he did (pleasantly) shock me by doing away with the alternate uniforms (and this from a marketing guy!).
